Navigation

Citrix Delivery Controller version 1808 is newer than Delivery Controller 7.18.

💡 = Recently Updated

Change Log

Upgrade

If you are performing a new install of Delivery Controller, then skip to the next section.

Starting in August 2018:

  • XenApp and XenDesktop is renamed to Citrix Virtual Apps and Desktops
  • Versioning changed to YYMM format. Version 1808 is newer than 7.18.

You can in-place upgrade directly from any Delivery Controller version 7.0 or newer. Citrix recommends upgrading Delivery Controller 5.6 to 7.6 LTSR Cumulative Update 6 before upgrading to 1808.

During the upgrade of Delivery Controller, be aware that a database upgrade is required. Either get a DBA to grant you temporary sysadmin permission, or use Citrix Studio to generate SQL scripts that a DBA must then run in SQL Studio.

  1. License Server Upgrade – Before upgrading to Delivery Controller 1808, if you have a standalone Citrix Licensing Server, upgrade it to 11.15.0.0 build 25000. The Delivery Controllers will be non-functional until you upgrade the License Server.
  2. Frequent updates/upgrades– Citrix Virtual Apps and Desktops 1808 is a Current Release.
    • With Current Release (CR), you’re expected to upgrade to the future version 1811 to receive bug fixes. Newer Current Releases come with new features, which might include new bugs. Current Releases are only supported for six months from the release date. That means you should plan to perform these upgrades at least twice a year.
    • If you don’t want to continuously upgrade to the latest Current Release, then you can stay on LTSR 7.15, which receives Cumulative Updates with bug fixes, but no new features. See Lifecycle Milestones for XenApp & XenDesktop.
  3. Delivery Controller OS Compatibility – 1808 Delivery Controller is supported on Windows 2012 R2 and newer. Windows Server 2008 R2 is no longer supported.
  4. VDA OS Compatibility – Virtual Delivery Agent (VDA) 1808 is only supported on a limited number of Windows operating system versions, specifically, Windows 10 (1607+), Windows Server 2012 R2, and Windows Server 2016.
    • If you have older VDA machines running Windows 7 or Windows Server 2008 R2, you can leave their VDA software at version 7.15 (with latest Cumulative Update). It is supported for VDA 7.15 to communicate with Delivery Controllers 1808.
  5. SCOM Agent – If StoreFront is installed on the Controller, and if the Citrix SCOM Agent for StoreFront is installed, stop the Citrix MPSF Agent service. See CTX220935 Cannot Perform a StoreFront Upgrade if Citrix SCOM Management Pack Agent Service is Running.
  6. Close PowerShell and Consoles. Make sure all Citrix Consoles and PowerShell consoles are closed. StoreFront won’t upgrade if any are running. If StoreFront fails, then the StoreFront configuration is wiped out.
  7. Other Users – Use Task Manager > Users tab to logoff any other user currently logged into the machine.
  8. Snapshot. If StoreFront is installed on the Controller, take a snapshot before attempting the upgrade.
  9. Download the Citrix Virtual Apps and Desktops 1808 ISO.
  10. Run AutoSelect.exe from the 1808 ISO.
  11. On the top left, click Studio and Server Components.
  12. In the Licensing Agreement page, select I have read, understand, and accept the terms, and click Next.
  13. In the Ensure Successful Upgrade page, read the steps, check the box next to I’m ready to continue, and click Next.
  14. If you see a License Errors page, then you need to upgrade your License Server.
  15. In the Preliminary Site Tests page, click Start Preliminary Tests.
  16. The tests will take a few minutes. Click Next when done.
  17. In the Firewall page, click Next.
  18. In the Summary page, click Upgrade.
  19. If you see a Running Processes window, close the listed programs, and click Continue.
  20. Click OK when asked to start the upgrade.
  21. The machine will probably reboot a couple times.
    1. After the reboot, and after logging in again, you might see a Locate ‘Citrix Virtual Apps and Desktops 7’ installation media window. Don’t click anything yet.
    2. Go to the Citrix_Virtual_Apps_and_Desktops_7_1808_2.iso file and mount it.
    3. Go back to the Locate ‘Citrix Virtual Apps and Desktops 7’ installation media window.
    4. On the left, expand This PC, and click the DVD Drive.
    5. Click Select Folder.
    6. Installation will resume. Repeat these instructions after each reboot.
  22. If the upgrade fails:
    1. Look for MetaInstaller log files under %localappdata%\Temp\Citrix\XenDesktop Installer\MSI Log Files.
    2. Look for StoreFront log files under C:\Program Files\Citrix\Receiver StoreFront\Admin\logs.
    3. Citrix has a MSI Log Analyzer.
  23. In the Smart Tools page, make a selection. If participating, click Connect, login with Citrix Cloud or mycitrix.com credentials, and then click Next. See Citrix Insight Services at Citrix Docs for more information on these options.
  24. In the Finish page, check the box next to Launch Studio, and click Finish.

Studio – Upgrade Database, Catalogs, and Delivery Groups

  1. In version 1808, Citrix Studio won’t connect to a Delivery Controller unless all Delivery Controllers are upgraded to 1808. Prior versions let you upgrade half your Delivery Controllers before upgrading the SQL databases. Version 1808 requires you to upgrade all of your Delivery Controllers at the same time before you can upgrade the SQL databases.
  2. After Citrix Studio launches, if you have sysadmin permissions on SQL, then click Start the automatic Site upgrade. If you don’t have full permission, then get a DBA to help you, click Manually upgrade this site, and follow the instructions.

  3. If you choose to Manually upgrade this site, then note that there might not be an upgrade for the Logging Database schema, depending on what version you are upgrading from.

  4. After all Controllers and VDAs are upgraded, right-click the Catalogs, and click Upgrade Catalog. Note: 7.9 is the newest minimum functional level. You won’t see an option for 1808. If your Catalogs are already set to VDA version 7.9, then there’s no need to upgrade the Catalogs or Delivery Groups.


  5. Then do the same for the Delivery Groups. Note: 7.9 is the newest minimum functional level. You won’t see an option for 1808. If your Delivery Groups are already set to VDA version 7.9, then no upgrade is needed.


Other Citrix Virtual Apps and Desktops components can also be in-place upgraded:

New Install Preparation

Frequent updates/upgrades

Citrix Virtual Apps and Desktops 1808 is a Current Release.

  • With Current Release (CR), you’re expected to upgrade to the future 1811 to receive bug fixes. Current Releases also come with new features, which might include new bugs. Current Releases are only supported for six months from the release date. That means you should plan to perform these upgrades at least twice a year.
  • If you don’t want to continuously upgrade to the latest Current Release, then you can stay on LTSR 7.15, which receives Cumulative Updates with bug fixes, but no new features. See Lifecycle Milestones for XenApp & XenDesktop.

VDA OS Compatibility

Delivery Controller 1808 is supported on Windows 2012 R2 and newer. Windows Server 2008 R2 is no longer supported.

Virtual Delivery Agent (VDA) 1808 is only supported on a limited number of Windows operating system versions, specifically, Windows 10 (1607+), Windows Server 2012 R2, and Windows Server 2016.

  • If you have older VDA machines running Windows 7 or Windows Server 2008 R2, you can install VDA software version 7.15. It is supported for VDA 7.15 to communicate with Delivery Controllers 1808.

Installation Automation

If you want to automate the install of Delivery Controllers, see Dennis Span Citrix Delivery Controller unattended installation with PowerShell and SCCM.

Citrix Licensing

If you are going to use an existing Citrix Licensing Server, upgrade it to 11.15.0.0 build 25000.

Multiple License Types – Multiple license types (but not multiple editions) are supported in a single farm. See CTX223926 How to Configure Multiple License Types within a Single XenApp and XenDesktop Site.

SQL Databases for Citrix Virtual Apps and Desktops

  • Citrix CTX209080 Database Sizing Tool for XenDesktop 7
  • Citrix article CTX114501 – Supported Databases for XenApp and XenDesktop Components
  • Three databases – There are typically three databases: one for the Site (aka farm), one for Logging (audit log) and one for Monitoring (Director).
    • The name of the monitoring database must not have any spaces in it. See CTX200325 Database Naming Limitation when Citrix Director Accesses Monitoring Data Using OData APIs
    • If you want Citrix Studio to create the SQL databases automatically, then the person running Studio must be a sysadmin on the SQL instances. No lesser SQL role will work. sysadmin permissions can be granted temporarily and revoked after installation.
    • As an alternative, you can use Citrix Studio to create SQL scripts, and then run those scripts on the SQL server. In that case, the person running the scripts only needs the dbcreator and securityadmin roles.
    • It is possible to create the three databases in advance. However, you must use the non-default Latin1_General_100_CI_AS_KS collation.
  • SQL High Availability Options:
    • Basic Availability Groups – Build two SQL 2016 (or newer) Standard Edition servers, and create three Basic Availability Groups, one for each database. Each Basic Availability Group has its own Listener.
    • Database Mirroring – Build two SQL 2014 or older Standard Edition servers, and configure Database Mirroring.
    • AlwaysOn Availability Group – Build two SQL Enterprise Edition servers, and create one AlwaysOn Availability Group with one Listener.
    • Failover Clustering – Build two SQL Enterprise Edition servers, and configure SQL Database Failover Clustering.
  • Cloud – Azure SQL and AWS RDS are not supported. You’ll need to build your own SQL Servers on IaaS VMs.

Windows Feature

Installing Group Policy Management on the Delivery Controllers lets you edit Citrix-targeted Group Policy Objects (GPOs) directly from the Controllers. Controllers already have Studio and Citrix Group Policy Management installed, so if GPMC runs from a Controller, then the GPO Editor will automatically have access to the Citrix Policies node. Or you can install Citrix Group Policy Management Plug-in on a different machine that has GPMC installed.

vCenter Service Account

Create a role in vSphere Client. Assign a service account to the role at the vCenter Datacenter or higher level. Delivery Controller will use this service account to login to vCenter.

Delivery Controller Install

  1. A typical size for the Controller VMs is 2-4 vCPU and 8+ GB of RAM. If all components (Delivery Controller, StoreFront, Licensing, Director, SQL Express) are installed on one server, then you might want to bump up memory to 10 GB or 12 GB.
  2. From Local Host Cache sizing and scaling at Citrix Docs:
    1. For LHC LocalDB, assign the Controller VMs a single socket with multiple cores.
    2. Add two cores for LHC.
    3. Add at least three more Gigs of RAM and watch the memory consumption.
    4. Since there’s no control over LHC election, ensure all Controllers have the same specs.
  3. Make sure the User Right Log on as a service includes NT SERVICE\ALL SERVICES, or add NT SERVICE\CitrixTelemetryService to the User Right.
  4. Download the Citrix Virtual Apps and Desktops 7 1808 ISO.
  5. On two Delivery Controllers, to install the Delivery Controller software, run AutoSelect.exe from the 1808 ISO.
  6. Click Start next to either Virtual Apps or Virtual Apps and Desktops. The only difference is the product name displayed in the installation wizard.
  7. On the top left, click Delivery Controller.
  8. In the Licensing Agreement page, select I have read, understand, and accept the terms, and click Next.
  9. In the Core Components page, you can install all components on one server, or on separate servers. Splitting out the components is only necessary in large environments, or if you have multiple farms and want to share the Licensing, StoreFront, and Director components across those farms. Click Next.
  10. In the Features page, uncheck the box next to Install Microsoft SQL Server 2014 SP2 Express, and click Next.
  11. In the Firewall page, click Next.
  12. In the Summary page, click Install.
  13. The machine will probably reboot a couple times.
    1. After the reboot, and after logging in again, you might see a Locate ‘Citrix Virtual Apps and Desktops 7’ installation media window. Don’t click anything yet.
    2. Go to the Citrix_Virtual_Apps_and_Desktops_7_1808_2.iso file and mount it.
    3. Go back to the Locate ‘Citrix Virtual Apps and Desktops 7’ installation media window.
    4. On the left, expand This PC, and click the DVD Drive.
    5. Click Select Folder.
    6. Installation will resume. Repeat these instructions after each reboot.
  14. In the Smart Tools page, make a selection. If you choose Smart Tools and Call Home, then click Connect, and enter your Citrix Cloud or MyCitrix.com credentials. Click Next.
  15. In the Finish page, click Finish. Citrix Studio will automatically launch.
  16. Ensure the two Delivery Controller VMs do not run on the same hypervisor host. Create an anti-affinity rule at vSphere Cluster > Manage > Settings > DRS Rules > Add. Set the Type to Separate Virtual Machines.

Create Site – Create Database

There are several methods of creating the databases for Citrix Virtual Apps and Desktops:

  • If you have sysadmin permissions to SQL, let Citrix Studio create the databases automatically.
  • If you don’t have sysadmin permissions to SQL, then use Citrix Studio to generate SQL scripts, and send the scripts to a DBA.

Use Citrix Studio to Create the Databases Automatically

  1. Launch Citrix Studio. After it loads, click Deliver applications and desktops to your users.
  2. In the Introduction page, select An empty, unconfigured site. This reduces the number of pages in this Setup wizard. The removed pages will be configured later.
  3. Enter a Site Name (aka farm name), and click Next. Only administrators see the farm name.
  4. In the Databases page, if you are building two Delivery Controllers, click Select near the bottom of the same page.
    1. Click Add.
    2. Enter the FQDN of the second Delivery Controller, and click OK. Note: the Delivery Controller software must already be installed on that second machine.
    3. Then click Save.
  5. If the person running Citrix Studio has sysadmin permissions to the SQL Server, then enter the SQL server name/instance in the three Location fields, and click Next.
  6. If you don’t have sysadmin permission, then jump to the SQL Scripts section below.
  7. On the Licensing page, enter the name of the Citrix License Server, and click Connect. If you installed Licensing with your Delivery Controller, then simply enter localhost.
  8. If the Certificate Authentication appears, select Connect me, and click Confirm.
  9. Select your license type, and click Next. If you see both User/Device and Concurrent, then you usually must select User/Device licenses. Also see CTX223926 How to Configure Multiple License Types within a Single XenApp and XenDesktop Site.
  10. In the Summary page, if your databases are mirrored or in an Availability Group, each database will show high availability servers, and the name of the Mirror server. Click Finish.

  11. It will take some time for the site to be created.
  12. Once done, skip to the Second Delivery Controller section.

Use Citrix Studio to create SQL scripts

  1. If you don’t have SQL sysadmin permissions, then change the selection to Generate scripts to manually set up databases on the database server. Change the database names if desired, and click Next.
  2. In the Summary page, click Generate scripts.
  3. A folder will open with six scripts. Edit each of the scripts.
  4. Near the top of each script are two lines to create the database. Uncomment both lines (including the go line). Then save and close the file.

  5. Once all of the scripts are edited, you can send them to your DBA.
    1. On the Principal SQL Server, open the file Site_Principal.sql.

    2. Open the Query menu, and click SQLCMD Mode to enable it.
    3. Then execute the script.
    4. If SQLCMD mode was enabled properly, then the output should look something like this:
    5. If you have a mirrored database, run the second script on the mirror SQL instance. Make sure SQLCMD mode is enabled.
    6. Repeat for the Logging_Principal.sql script.
    7. You’ll have to enable SQLCMD Mode for each script you open.


    8. Repeat for the Monitoring_Principal.sql script.
    9. Once again enable SQLCMD Mode.


    10. The person running Citrix Studio must be added to the SQL Server as a SQL Login, and granted the public server role, so that account can enumerate the databases.

  6. Back in Citrix Studio, click the Continue database configuration and Site setup button.
  7. In the Databases page, enter the SQL server name, and instance name, and click Next.

  8. On the Licensing page, enter the name of the Citrix License Server, and click Connect. If you installed Licensing with your Delivery Controller, then simply enter localhost.
  9. If the Certificate Authentication appears, select Connect me, and click Confirm.
  10. Then select your license, and click Next. See CTX223926 How to Configure Multiple License Types within a Single XenApp and XenDesktop Site.
  11. In the Summary page, if your databases are mirrored, each database will show high availability servers, and the name of the Mirror server. Click Finish.

  12. It will take some time for the site to be created.

Second Controller

When building the first Delivery Controller, the SQL scripts might have already included the second Delivery Controller, and thus no special SQL permissions are needed. If the second Delivery Controller has not already been added to the SQL databases, then there are several methods of adding a second Delivery Controller to the databases for Citrix Virtual Apps and Desktops:

  • If you have sysadmin permissions to SQL, let Citrix Studio modify the databases automatically.
  • If you don’t have sysadmin permissions to SQL then use Citrix Studio to generate SQL scripts and send them to a DBA.

To use Citrix Studio to create the SQL Scripts:

  1. On the first Delivery Controller, if StoreFront is installed on the Controller, then delete the default StoreFront store (/Citrix/Store), and recreate it with your desired Store name (e.g. /Citrix/CompanyStore).
  2. On the second Delivery Controller machine, install Delivery Controller as detailed earlier.
  3. After installation, launch Studio on the second controller, and click Connect this Delivery Controller to an existing Site.
  4. Enter the name of the first Delivery Controller, and click OK.
  5. If you don’t have full SQL permissions (sysadmin), click No when asked if you want to update the database automatically.
  6. Click Generate scripts.
  7. A folder will open with six scripts. If not mirroring, then the top three scripts need to be sent to a DBA. If mirroring, send all six.
  8. On the SQL Server, open one of the .sql files.

  9. Open the Query menu, and click SQLCMD Mode.
  10. Then execute the SQL script.
  11. If SQLCMD mode was enabled properly, then the output should look something like this:
  12. Repeat for the remaining script files.
  13. Back in Citrix Studio, click OK.
  14. In Citrix Studio, under Configuration > Controllers, you should see both controllers.

Studio – Slow Launch

From B.J.M. Groenhout at Citrix Discussions: The following adjustments can be made if Desktop Studio (and other Citrix management Consoles) will start slowly:

  • Within Internet Explorer, go to Tools – Internet Options – Tab Advanced – Section Security, and uncheck the option Check for publisher’s certificate revocation

After adjustment Desktop Studio (MMC) will be started immediately. Without adjustment it may take some time before Desktop Studio (MMC) is started.

Registry setting (can be deployed using Group Policy Preferences):

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing
    • “State“=dword:00023e00

Concurrent Logon Hard Limit

From Samuel Legrand XenApp 7.14 – (Really) Manage a DR! – Citrix Policies has a setting called Concurrent Logon Tolerance. However, it is not a hard limit, meaning once the limits are reached, it continues to let users connect. You can configure the Controllers to make it a hard limit by setting the following registry value:

  • HKLM\Software\Policies\Citrix\DesktopServer
    • LogonToleranceIsHardLimit (DWORD) = 1

Local Host Cache

If you have 10,000 or fewer VDAs per zone (up to 40,000 VDAs per multi-zone site/farm), you can enable Local Host Cache (LHC) instead of Connection Leasing. LHC allows new sessions to be started even if SQL database is unavailable.

From Local Host Cache sizing and scaling at Citrix Docs:

  1. For LHC LocalDB, assign the Controller VMs a single socket with multiple cores.
  2. Add two cores for LHC.
  3. Add at least three more Gigs of RAM and watch the memory consumption.
  4. Since there’s no control over LHC election, ensure all Controllers have the same specs.
  5. The Docs article has scripts for monitoring LHC performance.

From XenApp 7.12, LHC and a reboot at Citrix Discussions:

  • If the rebooted DDC is the elected one, a different DDC will take over (causing registration storm) and when the DDC gets back, it will take over brokering causing second registration storm. Site will sort itself out and all will work.
  • If the rebooted DDC is not the elected one, it will not impact any functionality.
  • If you turn the DDC down when site is working, and start it during outage, LHC will not trigger on that machine. This DDC will not impact the LHC unless it would become the elected one. In that scenario it will take control, however not start LHC and resources would not be available.

Trentent Tye at Citrix XenDesktop/XenApp 7.15 – The local host cache in action has a video showing LHC in action.

As mentioned by Citrix Docs, make sure PowerShell Execution Policy is set to RemoteSigned, Unrestricted, or Bypass.

If you did a fresh install of 1808, then Local Host Cache should be enabled by default. You can run Get-BrokerSite to confirm. (run asnp citrix.* first).

If not enabled, you can run some PowerShell commands to enable Local Host Cache:

asnp citrix.*
Set-BrokerSite -ConnectionLeasingEnabled $false
Set-BrokerSite -LocalHostCacheEnabled $true

George Spiers Local Host Cache XenApp & XenDesktop shows the Event Log entries when LHC is enabled.

Database Maintenance

Enable Read-Committed Snapshot

The Delivery Controller Database can become heavily utilized under load in a large environment. Therefore Citrix recommends enabling the Read_Committed_Snapshot option on the Delivery Controller databases to remove contention on the database from read queries. This can improve the interactivity of Studio and Director. It should be noted that this option may increase the load on the tempdb files. See Citrix article CTX137161 How to Enable Read-Committed Snapshot in XenDesktop for configuration instructions.

Change Database Connection Strings

Sometimes the database connection strings need to be modified:

  • When moving the SQL databases to a different SQL server
  • For AlwaysOn Availability Groups, to add MultiSubnetFailover to the SQL connection strings
  • For SQL mirroring, to add Failover Partner to the SQL connection strings

From Citrix Docs Update database connection strings when using SQL Server high availability solutions: Citrix offers several PowerShell scripts that update Delivery Controller database connection strings when you are using SQL Server high availability database solutions such as AlwaysOn and mirroring. The scripts, which use the Citrix Virtual Apps and Desktops PowerShell API, are:

  • DBConnectionStringFuncs.ps1: The core script that does the actual work. This script contains common functions that the other scripts use.
  • Change_XD_Failover_Partner_v1.ps1: Updates (adds, changes, or removes) the failover partner. This script prompts for the failover partner location (FQDN) for each database. (Providing a blank failover partner removes the failover partner. You can also use the ClearPartner option to remove a partner.) Do not set the failover partner to the same location as the principal database server.
  • Change_XD_To_ConnectionString.ps1: Uses the provided connection strings to update the connection strings to the databases. This script ensures that certain Citrix services are up and running, and then updates those services in the correct order on all Controllers in the site. Enclose connection string information for each database in quotes.
  • Change_XD_To_MultiSubnetFailover.ps1: Toggles the addition and removal of MultiSubnetFailover=true. If you use AlwaysOn Availability Groups, Microsoft recommends that the connection string include MultiSubnetFailover=true. This option speeds up recovery when a high availability event occurs, and is recommended for both single and multi-subnet environments. Run this script once to add the option. Run the script again to remove it.
  • Change_XD_To_Null.ps1: Resets all the connection strings on the localhost because something has gone wrong. By resetting the connection strings to null, this script places the Controller into an “initial” state. If you run Studio after running this script, you’ll be asked if you want to create a site or join an existing site. This is useful if something has gone wrong and a reset is needed. After the reset, you can try again to set the connection strings.

CTX140319 How to use PowerShell to Change XenDesktop SQL Connection Strings has the correctly ordered list of PowerShell commands to change the database connection strings. Make sure PowerShell is running as administrator before running these commands.

Here are the DB Connections that must be changed. This list might be longer than the article. When using the article, make sure you include all of the DB Connections shown below. You can get the full list of database commands by running Get-Command Set-*DBConnection. When changing the DB connections, AdminDBConnection must be the last to be set to NULL, and the first to be configured with the new connection string.

Set-ConfigDBConnection -DBConnection $null
Set-AppLibDBConnection –DBConnection $null    #7.8 and newer

Director Grooming

If your Citrix Virtual Apps and Desktops is not Premium Edition, then all historical Director data is groomed at 30 days.

For Citrix Virtual Apps and Desktops Premium Edition, by default, most of the historical Director data is groomed at 90 days. This can be adjusted up to 367 days by running a PowerShell cmdlet.

  1. On a Delivery Controller, run PowerShell elevated (as administrator), and run asnp Citrix.*
  2. Run Get-MonitorConfiguration to see the current grooming settings.
  3. Run Set-MonitorConfiguration to change the grooming settings.

View Logging Database

To view the contents of the Logging Database, in Studio, click the Logging node. On the right is Create Custom Report. See Citrix article CTX138132 Viewing Configuration Logging Data Not Shown for more info.

The Logging Database can be queried using Get-LogLowLevelOperation. See Stefan Beckmann Get user who set maintenance mode for a server or client for an example script that uses this PowerShell cmdlet.

Maintain Logging Database

Citrix CTX215069 Troubleshooting and managing Oversized Configuration Logging database: The article’s queries can be used to determine the number of configuration operation types performed by Citrix Virtual Apps and Desktops Administrator, and to analyze the content of the Configuration Logging database when it is considered oversized. A grooming query is also provided to delete data older than a specified date.

Export/Import Configuration

Ryan Butler has a PowerShell script that can export configuration from one Citrix Virtual Apps and Desktops farm and import it to another.

Kaspars Vilde at XenDesktop/XenApp 7.X Applications – Exporting / Importing at Citrix Discussions has scripts to export published apps from one farm and import to another farm.

Studio Administrators

Full Administrators

  1. In the Studio, under Configuration, click the Administrators node. The first time you access the node you’ll see a Welcome page. Feel free to check the box to Don’t show this again, and then click Close.
  2. On the Administrators tab, right-click, and click Create Administrator.
  3. In the Administrator and Scope page, Browse to a group (e.g. Citrix Admins) that will have permissions to Citrix Studio and Director. These groups typically have access to all objects, so select the All scope. Alternatively, you can create a Scope to limit the objects. Click Next.
  4. On the Role page, select a role, and then click Next. For example:
    • Full Administrator for the Citrix Admins group
    • Help Desk Administrator for the Help Desk group
    • Machine Catalog Administrator for the desktop team
  5. In the Summary page, click Finish.

Help Desk

  1. In Citrix Studio, under Configuration, click the Administrators node. On the Administrators tab, right-click, and click Create Administrator.
  2. In the Administrator and Scope page, Browse to a Help Desk group that will have permissions to Citrix Studio and Director. Select the All scope. And click Next.
  3. On the Role page, select the Help Desk Administrator role, and then click Next.
  4. In the Summary page, click Finish.
  5. When administrators in the Help Desk role log into Director, all they see is this.

    To jazz it up a little, add the Help Desk group to the read-only role.
  6. Right-click the Help Desk Administrator, and click Edit Administrator.
  7. Click Add.
  8. In the Scope page, select a scope, and click Next.
  9. In the Role page, select Read Only Administrator, and click Next.
  10. In the Summary page, click Finish.
  11. Then click OK. Now Director will display the dashboard.

Customer Experience Improvement Program

Citrix Virtual Apps and Desktops enables CEIP by default. If desired, you can disable it in Citrix Studio:

  1. On the left, go to the Configuration node.
  2. On the right, switch to the Product Support tab.
  3. Click End.
  4. Click Yes.

Citrix Studio collects data for Google Analytics. You can disable this in the registry at HKLM\Software\Citrix\DesktopStudio\GAEnabled = 0.

Each Citrix Virtual Apps and Desktops component has a separate configuration for disabling Customer Experience Improvement Program:

vCenter Connection

Citrix Virtual Apps and Desktops uses an Active Directory service account to log into VMware vCenter. This service account needs specific permissions in vCenter. To facilitate assigning these permissions, create a new vCenter role and assign it to the service account. The permissions should be applied at the vCenter datacenter or higher level.

Import vCenter Root Certificate

If the vCenter certificate is valid and trusted, then you can skip to the Hosting Resource section.

For newer versions of vCenter, you can import the root certificate that signed the vCenter Server/Appliance certificate.

  1. Point your browser to the root path of the vCenter Server URL.
  2. On the bottom right, click Download trusted root CA certificates.
  3. Extract the downloaded files.
  4. Go to \certs\win.
  5. Sort the files by date, and double-click the newest .crt file.
  6. On the General tab, click Install Certificate.
  7. In the Welcome to the Certificate Import Wizard page, change the Store Location selection to Local Machine, and click Next.
  8. In the Certificate Store page, click Browse.
  9. Select Trust Root Certification Authorities, and click OK.
  10. In the Completing the Certificate Import Wizard page, click Finish.
  11. If you close your browser and reopen it, and then go to the vCenter URL, there should no longer be any certificate errors.
  12. Skip to the Hosting Resource section.

Import vCenter Certificate

If the vCenter certificate is valid and trusted, then you can skip to the Hosting Resource section.

Alternatively, you can import the actual vCenter Server certificate (instead of the root). This is the only option for older self-signed vCenter certificates.

Newer versions of Citrix Virtual Apps and Desktops have the ability to import the vCenter certificate thumbprint into the database so every Delivery Controller trusts it. However, it is difficult to update the thumbprint whenever the vCenter certificate changes. It might instead be more reliable to use the older method of configuring the Trusted People store on the Delivery Controllers. Whenever the vCenter certificate is changed, you’ll need to repeat these steps.

  1. Get the vCenter certificate.
    1. Open a browser and point it to the vCenter URL. Note: this procedure to get the certificate won’t work in Internet Explorer.
    2. If Google Chrome, click the Secure box in the address bar, and then click Certificate.
    3. On the Details tab, click Copy to File.
    4. In the Welcome to the Certificate Export Wizard page, click Next.
    5. In the Export File Format page, either format will work. Click Next.
    6. In the File to Export page, browse to a new file, and click Next.
    7. In the Completing the Certificate Export Wizard page, click Finish.
  2. On the Delivery Controller, run certlm.msc. This opens the MMC console with the Certificates snap-in already added and pointing to Local computer.
  3. On the left, right-click the Trusted People node, expand All Tasks, and click Import.
  4. In the Welcome to the Certificate Import Wizard page, click Next.
  5. In the File to Import page, browse to the certificate you saved earlier, and click Next.
  6. In the Certificate Store page, click Next.
  7. In the Completing the Certificate Import Wizard page, click Finish.
  8. Click OK to acknowledge that the import was successful.
  9. Repeat these steps on the second Delivery Controller. It is important that you import the certificate on all Delivery Controllers before you add the Hosting Resource in Citrix Studio.
  10. If you open a browser and point o the vCenter Server, there should be no certificate errors.

Hosting Resources

A Hosting Resource = vCenter + Cluster (Resource Pool) + Storage + Network. When you create a machine catalog, you select a previously defined Hosting Resource, and the Cluster, Storage, and Network defined in the Hosting Resource object are automatically selected. If you need some VDA machines on a different Cluster+Storage+Network, then you’ll need to define more Hosting Resources in Studio.

  1. In Citrix Studio, expand Configuration and click Hosting. Right-click Hosting, and click Add Connection and Resources.
  2. In the Connection page, for Connection type, select VMware vSphere.
  3. Notice there’s a Learn about user permissions blue link to an article that describes the necessary permissions.
  4. Enter https://vcenter01.corp.local/sdk as the vCenter URL. The URL must contain the FQDN of the vCenter server.
  5. Enter credentials of a service account that can log into vCenter.
  6. In the Connection name field, give the connection a name. Typically, this matches the name of the vCenter server.
  7. If you are not using Machine Creation Services, and instead only need the vCenter connection for machine power management, change the Create virtual machines using selection to Other Tools.
  8. If you intend to use MCS, leave Create virtual machines using set to Studio Tools.
  9. Click Next.
  10. In the Storage Management page, click Browse, and select a vSphere cluster.
    • Note: as detailed at CTX223662, make sure there’s no comma in the datacenter name.
  11. Select Use storage shared by hypervisors.
  12. Beware of Optimize temporary data on available local storage. From Mark Syms at XA 7.9 MCS with RAM Caching at Citrix Discussions: “If you use just MCS caching to local storage then the VM is not agile at all and cannot be moved even when powered off as it has a virtual disk permanently associated with a single host.”
  13. Click Next.
  14. In the Storage Selection page, OS and Personal vDisk must be selected on at least one datastore.
    • For maximum virtual machine placement flexibility, only select one datastore per Hosting Resource. To select additional datastores, run this wizard again to create a separate Hosting Resource for each datastore.
    • When creating a Machine Catalog, you select a Hosting Resource. If the Hosting Resource only has one datastore selected, then you know which datastore the new VMs will be placed on. However, if the Hosting Resource has multiple datastores, then the datastores are selected round robin, and you don’t have any control over which datastore is selected for each new machine.
  15. If you selected the temporary data on local storage option, on the bottom, click Select, and choose the datastores you want to use for disk caching. By default, all local datastores are selected. Click Next when done.
  16. In the Network page, enter a name for the Hosting Resource. Since each Hosting Resource is a combination of vCenter, Cluster, Network, and Datastores, include those names in this field (e.g. vCenter01-Cluster01-Network01-Datastore01).
  17. Select a network and click Next.
  18. In the Summary page, click Finish.
  19. If you need to rename Storage, Network, or Datacenters in vCenter, see Citrix CTX225019 XA/XD 7.13: Renaming Storage, Network or Datacenters When Used With MCS or PVS. Either run Update-HypHypervisorConnection -LiteralPath "XDHyp:\Connections\MyConnection", or right-click the Hosting Resource and click Edit Storage. You can cancel the wizard.

If you have multiple datastores for your VDAs:

  1. Run the Add Connection and Resources wizard again.
  2. You can use the existing vCenter connection.
  3. This time, select a different datastore. Remember, don’t select more than one datastore per Hosting Resource.
  4. Give the Hosting Resource a name that indicates the chosen datastore.

When you later create a Machine Catalog:

  1. Select the Hosting Resource for the datastore where you want the VDAs to be placed.
  2. You can create multiple Machine Catalogs, with each of them on different datastores. You can then combine the Catalogs into a single Delivery Group.
  3. Later in the Catalog wizard, you’re given an option to enable caching and select a cache size. This is similar to Provisioning Services option “Cache in RAM with overflow to disk”. Note: MCS’s version of memory caching seems to cause performance problems.

Citrix VDA 1808 is newer than VDA 7.18

💡 = Recently Updated

Change Log

Hardware

Hypervisor Host Hardware

  • Citrix Blog Post Citrix Scalability — The Rule of 5 and 10: Simply take the number of physical cores in a hypervisor host, multiply it by 5 or 10, and the result will be your Single Server Scalability. Use 5 if you’re looking for the number of Virtual Desktop VMs you can host on a box, and use 10 if you’re looking for the number of Virtual Apps user sessions you can host on a box.

Virtual Machine Hardware

  1. Operating system version support: VDA 1808 supports Windows 10 (1607 and newer), Windows Server 2012 R2 (RDSH only), and Windows Server 2016 (RDSH or Server VDI).
    1. For older operating systems (e.g Windows 7 or Windows Server 2008 R2), install VDA 7.15 with the latest Cumulative Update. VDA 7.15 will work with newer Delivery Controllers (e.g. Delivery Controller 1808).
  2. Microsoft TechNet Blog – Say No to Windows 10 Long Term Servicing Channel (LTSC)
    • No Edge
    • From January 2020, Microsoft Office 365 will not be supported on LTSC
    • Non-security operating system fixes and enhancements may not get back-ported to LTSC
  3. CTX224843 Windows 10 compatibility with Citrix XenDesktop
  4. Firewall – the UDP-based EDT protocol is enabled by default. Make sure the UDP ports are open for ICA/HDX:
    1. UDP 1494
    2. UDP 2598
    3. UDP 443 – from Internet to NetScaler Gateway.
    4. UDP 443 can also be used by internal ICA connections if VDA SSL is configured.
    5. For EDT through NetScaler Gateway, make sure your NetScaler firmware is up to date, preferably 11.1 build 56 or newer. Then enable DTLS on the Gateway Virtual Server.
  5. VDA virtual machine sizing:
    1. For Windows 10 virtual desktops, give the virtual machine: 2+ vCPU and 2+ GB of RAM
    2. For Windows 2012 R2 RDSH, give the virtual machine 8 vCPU, and 24-48 GB of RAM
    3. See Daniel Feller Sizing Windows 2016, Windows 2012 And Windows 10 Virtual Machines
  6. If using RAM caching (MCSIO or PvS), add more RAM for the cache
  7. Remove the floppy drive
  8. Remove any serial or LPT ports
  9. If vSphere:
    1. To reduce disk space, reserve memory. Memory reservations reduce or eliminate the virtual machine .vswp file.
    2. The NIC should be VMXNET3.
  10. If this VDA will boot from Provisioning Services:
    1. For vSphere, the NIC must be VMXNET3.
    2. For vSphere, configure the CD-ROM to boot from IDE instead of SATA. SATA comes with VM hardware version 10. SATA won’t work with PvS.
  11. Install the latest version of hypervisor drivers (e.g. VMware Tools).
  12. The vSphere Activity Monitoring Feature with NSX Guest Introspection feature uses a TDI driver (vnetflt.sys), which might cause a “Connection Interrupted” message when users log off of Citrix. See CTX221206 “Connection Interrupted” error message displayed while logging off ICA session.

If vSphere, disable NIC Hotplug

  1. Users could use the systray icon to Eject the Ethernet Controller. Obviously this is bad.
  2. To disable this functionality, power off the virtual machine.
  3. Once powered off, right-click the virtual machine, and click Edit Settings.
  4. On the VM Options tab, expand Advanced, and then click Edit Configuration.
  5. On the bottom left, enter devices.hotplug. On the right, enter false. Then click Add.
  6. Then click OK a couple times to close the windows.
  7. The VM can then be powered on.

Windows Preparation

  1. Computer Group Policy – Make sure the Master VM is in the same OU as the Linked Clones so the Master VM will get the computer-level GPO settings in its registry. Run gpupdate on the master after moving the VM to the correct OU. When Clones are created from the Master, the computer-level GPO settings will already be applied, thus eliminating a timing issue.
  2. If Server OS, disable IE Enhanced Security Configuration in Server Manager > Local Server.
  3. Optionally, go to Action Center (Windows 2012 R2) or Control Panel > Security and Maintenance (Windows 10/2016) to disable User Account Control, and enable SmartScreen.
    1. In Windows 10 1703 and newer, search the Settings app for Change User Account Control settings.
    2. SmartScreen is configured in Windows Defender Security Center > App & browser control.
  4. Run Windows Update. Do not skip this step. Many VDA installation problems are fixed by simply updating Windows.


    1. Defer Feature Updates – For Windows 10, since Citrix VDA does not immediately support new Windows 10 versions, configure Windows Update to defer feature updates.


  5. Add your Citrix Administrators group to the local Administrators group on the VDA. Computer Management.
  6. The Remote Desktop Services “Prompt for Password” policy prevents Single Sign-on to the Virtual Delivery Agent. Check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services. If fPromptForPassword = 1 then you need to fix group policy. The following GPO setting will prevent Single Sign-on from working.
    Computer Configuration | Policies | Administrative Templates | Windows Components | Remote Desktop Services | Remote Desktop Session Host | Security | Always prompt for password upon connection
    Or set the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Portica\AutoLogon (DWORD) = 0x1. This registry value only applies to Desktop OS, not Server OS. (source = comments)
  7. To remove the built-in apps in Windows 10, see Robin Hobo How to remove built-in apps in Windows 10 Enterprise.
  8. For Remote Assistance in Citrix Director, configure the GPO setting Computer Configuration | Policies | Administrative Templates | System | Remote Assistance | Offer Remote Assistance. See Jason Samuel – How to setup Citrix Director Shadowing with Remote Assistance using Group Policy for more details.
  9. If you intend to use Citrix’s SCOM Management Packs for XenApp/XenDesktop, make sure WinRM is enabled on the VDA by running winrm quickconfig. Or you can enable WinRM using Group Policy.

Install Virtual Delivery Agent 1808

  1. For virtual desktops, make sure you are logged into the console. The VDA won’t install if you are connected using RDP.
  2. VDA will install .NET Framework 4.7.1 for you.

CLI Install:

Command Line Install Options are detailed at Install using the command line at Citrix Docs.

The Citrix Telemetry Service seems to cause problems. You can use the Command Line Installer to exclude Telemetry Service as detailed at VDA upgrade cmdlet at Citrix Discussions.

XenDesktopVDASetup.exe /quiet /noreboot /masterimage /Enable_HDX_PORTS /enable_framehawk_port /Enable_REAL_TIME_TRANSPORT /optimize /controllers "xdc01.corp.local xdc02.corp.local" /Exclude "Citrix Telemetry Service"

Citrix Blog Post Citrix VDA Commandline Helper Tool: a GUI to configure the VDA installation options.

GUI Install:

  1. Mount the downloaded Citrix Virtual Apps and Desktops 7 1808 ISO, and and run AutoSelect.exe.
    • Alternatively, you can download the standalone VDA package and run that instead. Go the main Citrix Virtual Apps and Desktops 7 1808 download page. Expand the section labelled Components that are on the product ISO but also packaged separately. There is also a VDA installer called Desktop OS Core Services that is designed for Remote PC deployments.
  2. Click Start next to either Virtual Apps or Virtual Apps and Desktops. The only difference is the product name displayed in the installation wizard.

Citrix Desktop Helper Service

Citrix Blog Post Augment Your XenDesktop Deployment with the Desktop Helper Service: this installable service adds the following functionality to your VDAs:

  • The “Shutdown Inactive Desktops” feature allows Citrix administrators to enable a timer that shuts down a virtual desktop after it has been registered for a configured amount of minutes without a user connection.
  • Delaying the Citrix Desktop Service start by a configurable amount of time allows the desktop to finish performing on-boot tasks before a user is brokered to it.
  • The “Force Group Policy Update” feature give administrators the ability to force a group policy update after a configured amount of time.

If these features are desirable, download the tool from the blog post and install it.

Configurable Registry keys are located at HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\DesktopHelper. Each value is detailed in the accompanying Word document.

Customer Experience Improvement Program (CEIP)

Customer Experience Improvement Program (CEIP) is enabled by default. To disable it, create the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Telemetry\CEIP\Enabled (DWORD), and set it to 0 (zero). Also see CEIP at Citrix Insight Services at Citrix Docs.

See http://www.carlstalhood.com/delivery-controller-1808-and-licensing/#ceip for additional places where CEIP is enabled.

Connection Quality Indicator

The Connection Quality Indicator tells the user the quality of the connection. Position of the indicator is configurable by the user. Thresholds are configurable through group policy.

Download it from CTX220774 Connection Quality Indicator and install it. The article is very detailed.

Group Policy templates are located at C:\Program Files (x86)\Citrix\Connection Quality Indicator\Configuration. Copy the files and folder to <Sysvol>\Policies\PolicyDefinitions, or C:\Windows\PolicyDefinitions.

Find the settings under Computer Config | Policies | Administrative Templates | Citrix Components | Virtual Desktop Agent | CQI

Version 1.2 adds the GPO settings to the user half of a GPO, which lets you disable CQI for some users and enable it for others.

Notification display settings lets you customize the user notifications, or disable them.

Connection Threshold Settings lets you set the notification thresholds.

Adaptive Transport

Adaptive Transport is a HDX/ICA protocol feature that tries to use UDP ports (EDT protocol) if they are open, and falls back to TCP ICA if UDP connection is not successful. On higher latency connections, EDT (UDP) tends to perform better than traditional TCP ICA.

The Citrix Policy setting HDX Adaptive Transport defaults to Preferred, which means Adaptive Transport is enabled by default.

The newer Citrix EDT protocol use UDP Ports 1494/2598 for HDX connections to the VDA. The UDP ports should already be open in the VDA’s Windows Firewall. In other words, HDX/ICA uses both TCP and UDP ports.

For EDT (and Adaptive Transport) through NetScaler Gateway, make sure your NetScaler firmware is up to date, preferably 11.1 build 56 or newer. Then make sure DTLS is enabled on the Gateway Virtual Server. DTLS is the UDP version of SSL/TLS.

Slow Logons

Citrix Discussions Xenapp 7.9: Wait for local session manager: “I have a Xenapp 7.9 environment on Windows 2012 R2. When logging in through Citrix I got message “Wait for local session manager” for 20-30 seconds. When logging in to the server with RDS, I do not have to wait for this.”

“Add the following 2 registry keys to your VDA server – then try connecting to it using ICA to see if the issue still occurs:

Add reg keys in “HKLM\SOFTWARE\Citrix\GroupPolicy”
Dword: “CacheGpoExpireInHours” – Value = 5-24 (# of Hours) ***start with value of 5***
Dword: “GpoCacheEnabled” – Value = 1

Restart the machine after adding these registry keys and attempt an ICA connection (at least twice) to see if that helps the Login delay.”

 

Marvin Neys at XenApp slow logon times, user get black screen for 20 seconds at Citrix Discussions says that deleting HKCU\Software\Microsoft\Windows\CurrentVersion\UFH\SHC at logoff reduces logon times from 40 seconds to 6 seconds.

Remove-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\UFH\SHC

 

For additional logon delay troubleshooting, see Alexander Ollischer XenApp/XenDesktop – “Please Wait For Local Session Manager” message when logging into RDS. He found some Windows Updates that caused a logon delay.

 

VDA recalculates WMI filters on every reconnect. CTX212610 Session Reconnect 30 sec Delay – DisableGPCalculation – WMI Filters indicates that recalculation can be disabled by setting HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Reconnect\DisableGPCalculation (DWORD) to 1.

Controller Registration Port

Some environments will not accept the default port 80 for Virtual Delivery Agent registration, even though registration is authenticated and encrypted on port 80. To change the port, do the following on the Virtual Delivery Agent:

  1. Open Programs and Features. If Windows 10 1703 or newer, open Apps and Features.
  2. Find Citrix Virtual Delivery Agent , and click Change or Modify (Windows 10 1703 and newer).

  3. Click Customize Virtual Delivery Agent Settings.
  4. Edit the Delivery Controllers, and click Next.
  5. On the Protocol and Port page, change the port number, and click Next.
  6. In the Summary page, click Reconfigure.
  7. If you see a Smart Tools page, make a selection for Call Home, and click Next.
  8. In the Finish Reconfiguration page, click Finish.
  9. Restart the VDA machine.
  10. You must also change the VDA registration port on the Delivery Controllers by running BrokerService.exe /VDAPort.
  11. For Local Host Cache, on the Delivery Controller, run C:\Program Files\Citrix\Broker\Service\HighAvailabilityService.exe –VdaPort <CORRECT PORT #>. Source = CTX229493 VDAs Do Not Register in LHC Mode When Registration Port is Not Set To Default.

Verify that VDA registered with a Controller

  1. If you restart the Virtual Delivery Agent machine, or restart the Citrix Desktop Service…
  2. In Windows Logs > Application log, you should see an event 1012 from Citrix Desktop Service saying that it successfully registered with a controller.
  3. If you don’t see successful registration, then you’ll need to fix the ListOfDDCs registry key.
    1. See VDA registration with Controllers at Citrix Docs.
    2. See The Most Common VDA Registration Issues & Troubleshooting Steps at Citrix Blogs.
  4. You can also run Citrix’s Health Assistant on the VDA.

  5. See CTX220772 Technical Primer: VDA Registration for a very detailed explanation of the VDA Registration process.

Citrix PDF Printer  for Receiver for HTML5/Chrome

  1. VDA 1808 installs the PDF Printer automatically so there’s no need for a separate installation.
  2. To enable the PDF printer for HTML5 connections, configure the Citrix Policy setting called Auto-create PDF Universal Printer in the user half of a Citrix Policy GPO.

Citrix File Access 2.0.3 for Receiver for Chrome

  1. If you support Receiver for Chrome (Chromebook) and want published applicatons to open files on Google Drive, install Citrix File Access on the VDAs. Get it from the Receiver for Chrome download page, in the Additional Components section.
  2. Go to the extracted Citrix_File_Access_2.0.3, and run FileAccess.msi.
  3. In the Please read the File Access License Agreement page, check the box next to I accept the terms, and click Install.
  4. In the Completed the File Access Setup Wizard page, click Finish.
  5. File Access is listed in Programs and Features (or Apps & Features) as version 2.0.3.33.

  6. File Access has a default list of supported file extensions. The list can be expanded by editing the registry on the VDA. See CTX219983 Receiver for Chrome Error: Invalid command line arguments: Unable to open the file as it has an unsupported extension.
  7. To open a file from Google Drive, right-click and and open the file using Citrix Receiver.

Remote Desktop Licensing Configuration

On 2012 R2 and newer RDSH, the only way to configure Remote Desktop Licensing is using group policy (local or domain). This procedure is not needed on virtual desktops.

  1. For local group policy, run gpedit.msc. Alternatively, you can configure this in a domain GPO.
  2. Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Licensing.
  3. Double-click Use the specified Remote Desktop license servers. Change it to Enabled, and enter the names of the RDS Licensing Servers (typically installed on Delivery Controllers). Click OK.
  4. Double-click Set the Remote Desktop licensing mode. Change it to Enabled and select Per User. Click OK.
  5. Optionally, you can install the Remote Desktop Licensing Diagnoser Tool. In the Server Manager > Add Roles and Features Wizard, on the Features page, expand Remote Server Administration Tools, expand Role Administration Tools, expand Remote Desktop Services Tools, and select Remote Desktop Licensing Diagnoser Tool. Then Finish the wizard.
  6. If it won’t install from Server Manager, you can install it from PowerShell by running Install-WindowsFeature rsat-rds-licensing-diagnosis-ui.
  7. In Server Manager, open the Tools menu, expand Remote Desktop Services (or Terminal Services), and click Remote Desktop Licensing Diagnoser.

  8. The Diagnoser should find the license server, and indicate the licensing mode. If you’re configured for Per User licenses, then it’s OK if there are no licenses installed on the Remote Desktop License Server.

Several people in Citrix Discussions reported the following issue: If you see a message about RD Licensing Grace Period has expired even though RD Licensing is properly configured, see Eric Verdumen No remote Desktop Licence Server availible on RD Session Host server 2012. The solution was to delete the REG_BINARY in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod only leaving the default. You must take ownership and give admin users full control to be able to delete this value.

C: Drive Permissions

This section is more important for shared VDAs like RDSH (Windows Server 2012 R2, and Windows Server 2016).

The default permissions allow users to store files on the C: drive in places other than their profile.

  1. Open the Properties dialog box for C:.
  2. On the Security tab, click Advanced.
  3. If UAC is enabled, click Change permissions.
  4. Highlight the line containing Users and Create Folders, and click Remove.
  5. Highlight the line containing Users and Create files (or Special), and click Remove. Click OK.
  6. Click Yes to confirm the permissions change.
  7. If you see any of these Error Applying Security windows, click Continue. This window should appear multiple times.
  8. Click OK to close the C: drive properties.

Pagefile

If this image will be converted to a Provisioning Services vDisk, then you must ensure the pagefile is smaller than the cache disk. For example, if you allocate 20 GB of RAM to your Remote Desktop Session Host, and if the cache disk is only 15 GB, then Windows will have a default pagefile size of 20 GB, and Provisioning Services will be unable to move it to the cache disk. This causes Provisioning Services to cache to server instead of caching to your local cache disk (or RAM).

  1. Open System. In 2012 R2 and newer, you can right-click the Start button, and click System. Note: in Windows 10 1703 and newer, this method no longer opens the correct tool.
  2. Another option is to open File Explorer, right-click This PC, and click Properties. This works in Windows 10 1703.
  3. Click Advanced system settings.
  4. On the Advanced tab, click the top Settings button.
  5. On the Advanced tab, click Change.
  6. Uncheck the box next to Automatically manage paging file size for all drives. Then either turn off the pagefile, or set the pagefile to be smaller than the cache disk. Don’t leave it set to System managed size. Click OK several times.

Direct Access Users

When Citrix Virtual Delivery Agent is installed on a machine, non-administrators can no longer RDP to the machine. A new local group called Direct Access Users is created on each Virtual Delivery Agent. Add your non-administrator RDP users to this local group so they can RDP directly to the machine.

From CTX228128 What is the HKLM\Software\Citrix\PortICA\DirectAccessUsers registry function: The HKLM\Software\Citrix\PortICA\DirectAccessUsers registry key determines which Local group the VDA references to determine if a user should be allowed Unbrokered RDP access. Members of the Local Administrators group will always be granted access. If the Registry Key does not exist, or gets deleted, VDA will always allow the Unbrokered RDP Connection. The Registry key and local group are created as part of the VDA installation process.

Windows Profiles v3/v4/v5/v6

Roaming Profiles are compatible only between the following client and server operating system pairs. The profile version is also listed.

  • v6 = Windows 10 (1607 and 1703) and Windows Server 2016
  • v5 = Windows 10 (1511 and older)
  • v4 = Windows 8.1 and Windows Server 2012 R2
  • v3 = Windows 8 and Windows Server 2012
  • v2 = Windows 7 and Windows Server 2008 R2
  • v2 = Windows Vista and Windows Server 2008

For Windows 2012 R2, install Microsoft hotfix 2890783, and set the UseProfilePathExtensionVersion registry value to 1.

CTX230343 Reset Profile Options Is Greyed Out In Citrix Director states that the UseProfilePathExtensionVersion registry value is required on Windows 2012 R2 to enable Director users to reset profiles.

From Citrix CTX205214 Screensaver Not Working in XenDesktop: By default, Screen Saver doesn’t work on Desktop OS. To enable it, on the VDA, configure the following registry value:

  • Key = HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Graphics
    • Value (DWORD) = SetDisplayRequiredMode = 0

Smart Cards

From CTX231942 Windows 10 April 2018 Update (v1803) – Citrix Known Issues – Smart Card Service (SCardSvr) will run only if a Smart Card reader is connected. As ICA sessions redirect the Smart Card, it finds the service not to be running and fails.

  • Key = HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\Cryptography\Calais
    • Value (DWORD) = AllowServiceAccessWithNoReaders = 1

Logon Disclaimer Window Size

From XenApp 7.8 – Session Launch Security/Warning Login Banner at Citrix Discussions: If your logon disclaimer window has scroll bars, set the following registry values:

  • Key = HKEY_LOCAL_MACHINE\Software\Wow6432node\Citrix\CtxHook\AppInit_DLLS\Multiple Monitor Hook
    • Value (DWORD) = LogonUIWidth = 300
    • Value (DWORD) = LogonUIHeight = 200

  •  Key = HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI
    • Value (DWORD) =ApplicationLaunchWaitTimeoutMS = decimal 60000

Receiver for HTML5/Chrome Enhanced Clipboard

From About Citrix Receiver for Chrome 1.9 at Citrix Docs: To enable enhanced clipboard support, create a REG_SZ registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard\Additional Formats\HTML Format\Name=”HTML Format”. Create any missing registry keys. This applies to both virtual desktops and Remote Desktop Session Hosts.

Receiver for HTML5/Chrome Upload Folder

The Receiver for HTML5 (or Chrome) lets upload files.

By default, the user is prompted to select a upload location. If you use the Upload feature multiple times, the last selected folder is not remembered.

Citrix CTX217351 How to Customize File Upload and Download Using Receiver for HTML5 and Receiver for Chrome. You can specify a default uploads location by editing HKLM\Software\Citrix\FileTransfer\UploadFolderLocation on the VDA. Environment variables are supported. When this value is configured, users are no longer prompted to select an upload location. The change takes effect at next logon.

Note: HTML5/Chrome Receiver also adds a Save to My Device location to facilitate downloads.

4K Monitors

From Citrix Knowledgebase article CTX218217 Unable to span across multiple monitors after upgrade to 7.11 VDA, Black/Blank screen appears on the monitors while connecting to ICA session:

  1. Calculate the video memory that is required for monitors using the following formula:
    SumOfAllMons (Width * Height) * 4 / 0.3, where width and height are resolution of the monitor. Note: There is no hard and fast rule that will work for all cases.
    Example: Consider the resolution of monitor 1 is 1920*1200 and monitor 2 is 1366*768. Then SumOfAllMons will be (1920*1200 + 1366*768)
  2. CTX115637 Citrix Session Graphics Memory Reference describes how multi-monitor resolution is determined.
  3. Open the registry (regedit) and navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\vbdenum
  4. Increase the value of “MaxVideoMemoryBytes” REG_DWORD value to the above calculated memory.
  5. Reboot the VDA.

Citrix Policies also control graphics performance.

COM Port Threads

CTX212090 COM Port Intermittently Inaccessible During ICA Sessions: increase the default value of “MaxThreads” under the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\picaser\Parameters from 20 to a value greater than the number of COM port connections you want to support. For example, if a VDA server supports 100 sessions and each session opens two COM ports, the value of “MaxThreads” should be greater than 200.

NVIDIA GRID License

Allow NVIDIA GRID License to apply after the session is started. (Source = Jan Hendrik Meier NVIDIA GRID license not applied before the user connects – License Restriction will not be removed until the user reconnects)

  • Key = HKLM\SOFTWARE\NVIDIA Corporation\Global\GridLicensing
    • Value (DWORD) = IgnoreSP = 1

Legacy Client Drive Mapping

Citrix CTX127968 How to Enable Legacy Client Drive Mapping Format on XenApp: Citrix Client Drive Mapping no longer uses drive letters and instead they appear as local disks. This is similar to RDP drive mapping.

The old drive letter method can be enabled by setting the registry value:

  • Key = HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\UncLinks (create the key)
    • Value (DWORD) = UNCEnabled = 0

When you reconnect, the client drives will be mapped as drive letters (starts with V: and goes backwards).

Print Driver for Non-Windows Clients

From CTX140208 Client printing from Mac and Linux clients on Windows 10, Server 2012 R2, and Server 2016. By default, Non-Windows clients cannot map printers due to a missing print driver on the VDA machine.

  1. Requirements:
    • Internet Access
    • Windows Update service enabled
  2. Click Start, and run Devices and Printers.
    1. In Windows 10 1703, open Printers & scanners, then scroll down, and click Devices and printers.

  3. In the Printers section, highlight a local printer (e.g. Microsoft XPS Document Writer). Then in the toolbar, click Print server properties.

  4. Switch to the Drivers tab. Click Change Driver Settings.
  5. Then click Add.
  6. In the Welcome to the Add Printer Driver Wizard page, click Next.
  7. In the Processor Selection page, click Next.
  8. In the Printer Driver Selection page, click Windows Update. The driver we need won’t be in the list until you click this button. Internet access is required.
  9. Once Windows Update is complete, highlight HP on the left, and then select HP Color LaserJet 2800 Series PS (Microsoft) on the right. Click Next.
  10. In the Completing the Add Printer Driver Wizard page, click Finish.
  11. Repeat these instructions to install the following additional drivers:
    • HP LaserJet Series II
    • HP Color LaserJet 4500 PCL 5

SSL for VDA

If you intend to use HTML5 Receiver internally, install certificates on the VDAs so the WebSockets (and ICA) connection will be encrypted. Internal HTML5 Receivers will not accept clear text WebSockets. External users don’t have this problem since they are SSL-proxied through NetScaler Gateway.

Notes:

  • Each Virtual Delivery Agent needs a machine certificate that matches the machine name. This is feasible for a small number of persistent VDAs. For non-persistent VDAs, you’ll need some automatic means for creating machine certificates every time they reboot.
  • As detailed in the following procedure, use PowerShell on the Controller to enable SSL for the Delivery Group. This forces SSL for every VDA in the Delivery Group, which means every VDA in the Delivery Group must have SSL certificates installed.

The following instructions for manually enabling SSL on VDA can be found at Configure TLS on a VDA using the PowerShell script at Citrix Docs.

  1. On the VDA machine, run certlm.msc.
  2. Right-click Personal, expand All Tasks, and click Request New Certificate to request a certificate from your internal Certificate Authority. You can use either the Computer template or the Web Server template.
    • You can also use group policy to enable Certificate Auto-Enrollment for the VDA computers.
  3. Browse to the Citrix Virtual Apps and Desktops ISO. In the Support\Tools\SslSupport folder, shift+right-click the Enable-VdaSSL.ps1 script, and click Copy as path.
  4. Run PowerShell as administrator (elevated).
  5. Run the command Set-ExecutionPolicy unrestricted. Enter Y to approve.
  6. In the PowerShell prompt, type in an ampersand (&), and a space.
  7. Right-click the PowerShell prompt to paste in the path copied earlier.
  8. At the end of the path, type in -Enable
  9. If there’s only one certificate on this machine, press Enter.
  10. If there are multiple certificates, then you’ll need to specify the thumbprint of the certificate you want to use. Open the Certificates snap-in, open the properties of the machine certificate you want to use, and copy the Thumbprint from the Details tab.
    In the PowerShell prompt, at the end of the command, enter ‑CertificateThumbPrint, add a space, and type quotes (").
    Right-click the PowerShell prompt to paste the thumbprint.
    Type quotes (") at the end of the thumbprint. Then remove all spaces from the thumbprint. The thumbprint needs to be wrapped in quotes.
  11. There are additional switches to specify minimum SSL Version and Cipher Suites. Also see Citrix CTX226049 Disabling Triple DES on the VDA breaks the VDA SSL connection.
  12. Press <Enter> to run the Enable-VdaSSL.ps1 script.
  13. Press <Y> twice to configure the ACLs and Firewall.
  14. You might have to reboot before the settings take effect.
  15. Login to a Controller, and run PowerShell as Administrator (elevated).
  16. Run the command asnp Citrix.*
  17. Enter the command: 
    Get-BrokerAccessPolicyRule -DesktopGroupName '<delivery-group-name>' | Set-BrokerAccessPolicyRule ‑HdxSslEnabled $true

    where <delivery-group-name> is the name of the Delivery Group containing the VDAs.

  18. You can run Get-BrokerAccessPolicyRule -DesktopGroupName '<delivery-group-name>' to verify that HDX SSL is enabled.
  19. Also run the following command to enable DNS resolution. 
    Set-BrokerSite –DnsResolutionEnabled $true

  20. Since the UDP-based EDT protocol is enabled by default, open port UDP 443 to the VDAs.

You should now be able to connect to the VDA using the HTML5 Receiver from internal machines.

The Citrix blog post How To Secure ICA Connections in XenApp and XenDesktop 7.6 using SSL has a method for automatically provisioning certificates for pooled virtual desktops by enabling certificate auto-enrollment and setting up a task that runs after the certificate has been enrolled.

  • From Russ Hargrove at A note on VDA certificates in 7.14 at Citrix Discussions: Citrix installs a new “Citrix XenApp/XenDesktop HDX Service” certificate in the Personal store which breaks the automation of the Enable-VdaSSL.ps1 script. To fix the problem, modify the task scheduler powershell script to: 
    Enable-VdaSSL.ps1 -Enable -CertificateThumbPrint (Get-ChildItem -path cert:\LocalMachine\My | Where-Object -FilterScript {$_.Subject -eq ""} | Select-Object -ExpandProperty Thumbprint) -Confirm:$False
  • For certificate auto-enrollment on non-persistent Remote Desktop Session Hosts (aka Server OS VDAs), see Non-Persistent Server SSL to VDA by Alfredo Magallon Arbizu at CUGC.

Anonymous Accounts

If you intend to publish apps anonymously then follow this section.

  1. Anonymous accounts are created locally on the VDAs. When VDA creates Anon accounts, it gives them an idle time as specified at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\AnonymousUserIdleTime. The default is 10 minutes. Adjust as desired.
  2. Pre-create the Anon accounts on the VDA by running "C:\Program Files\Citrix\ICAConfigTool\CreateAnonymousUsersApp.exe". If you don’t run this tool, then anonymous users can’t login.
  3. You can see the local Anon accounts by opening Computer Management, expanding System Tools, expanding Local Users and Groups and clicking Users.
  4. If you want profiles for anonymous users to delete at logoff, then you’ll need to add the local Anon users to the local Guests group.
  5. If you open one of the accounts, on the Sessions tab, notice that idle timeout defaults to 10 minutes. Feel free to change it.

Group Policy for Anonymous Users

Since Anonymous users are local accounts on each Virtual Delivery Agent, domain-based GPOs will not apply. To work around this limitation, you’ll need to edit the local group policy on each Virtual Delivery Agent.

  1. On the Virtual Delivery Agent, run mmc.exe.
  2. Open the File menu, and click Add/Remove Snap-in.
  3. Highlight Group Policy Object Editor, and click Add to move it to the right.
  4. In the Welcome to the Group Policy Wizard page, click Browse.
  5. On the Users tab, select Non-Administrators.
  6. Click Finish.
  7. Now you can configure group policy to lockdown sessions for anonymous users. Since this is a local group policy, you’ll need to repeat the group policy configuration on every Virtual Delivery Agent image. Also, Group Policy Preferences is not available in local group policy.

Citrix’s Recommended Antivirus Exclusions

Citrix Blog Post Citrix Recommended Antivirus Exclusions: the goal here is to provide you with a consolidated list of recommended antivirus exclusions for your Citrix virtualization environment focused on the key processes, folders, and files that we have seen cause issues in the field:

  • Set real-time scanning to scan local drives only and not network drives
  • Disable scan on boot
  • Remove any unnecessary antivirus related entries from the Run key
  • Exclude the pagefile(s) from being scanned
  • Exclude Windows event logs from being scanned
  • Exclude IIS log files from being scanned

See the Blog Post for exclusions for each Citrix component/product including: StoreFront, VDA, Controller, and Provisioning Services. The Blog Post also has links to additional KB articles on antivirus.

Trend Micro

Trend Micro Slow login on Citrix environment after installing OfficeScan (OSCE): The following registries can be used to troubleshoot the issue. These registries will allow a delay on the startup procedure of OSCE until the system has launched successfully. This avoids deadlock situations during login.

Citrix CTX136680 – Slow Server Performance After Trend Micro Installation. Citrix session hosts experience slow response and performance more noticeable while users try to log in to the servers. At some point the performance of the servers is affected, resulting in issues with users logging on and requiring the server to be restarted. This issue is more noticeable on mid to large session host infrastructures.

Trend Micro has provided a registry fix for this type of issue. Create the following registry on all the affected servers. Add new DWORD Value as:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TmFilterParameters] “DisableCtProcCheck”=dword:00000001

Sophos Anti-Virus for Windows 2000+: incorporating current versions in a disk image, including for use with cloned virtual machines: This procedure will make sure that the produced target/cloned computers:

  • Get their distinct identity with Enterprise Console, under which they can be subsequently managed.
  • Have the desired version of Sophos Anti-Virus already installed and configured on the created image.

Cylance

CTX232722 Unable to launch application with Cylance Memory Protection Enabled. Cylance must be run in compatibility mode in order to the VDA and Cylance to run on the same machine. See the article for detailed instructions.

Optimize Performance

VDA Optimizer

Installation of the VDA might have already done this, but there’s no harm in doing it again. This tool is only available if you installed VDA in Master Image mode.

  1. On the master VDA, go to C:\Program Files\Citrix\PvsVm\TargetOSOptimizer, and run TargetOSOptimizer.exe.
  2. Then click OK. Notice that it disables Windows Update.
  3. See CTX125874 How to Optimize XenDesktop Machines for the list of registry values changed by the TargetOSOptimizer tool. You can use Group Policy Preferences to set these values.

Windows 10 / Windows 2012 R2 / Windows 2016 and newer

Optimization Notes:

Seal and Shut Down

If this VDA will be a master image in a Machine Creation Services or Citrix Provisioning catalog, after the master is fully prepared (including applications), do the following:

  1. Go to the properties of the C: drive, and run Disk Cleanup.
  2. If Disk Cleanup is missing, you can run cleanmgr.exe instead.
  3. Windows 10 1703 and newer has a new method for cleaning up temporary files.
    1. Right-click the Start button, and click System.
    2. Click Storage on the left, and click This PC (C:) on the right.
    3. Click Temporary Files.
    4. Check boxes, and click Remove files.
  4. On the Tools tab, click Optimize to defrag the drive.
    `
  5. Run slmgr.vbs /dlv and make sure it is licensed with KMS and has at least one rearm remaining. It is not necessary to manually rearm licensing since MCS will do it automatically.
  6. Run Delprof2 to clean up local profiles. Get it from http://helgeklein.com/download/.
  7. Machine Creation Services and Provisioning Services require DHCP.
  8. Session hosts (RDSH) commonly have DHCP reservations.
  9. Login Base Image Script Framework (BIS-F) automates many sealing tasks. The script is configurable using Group Policy.
  10. Shut down the master image. You can now use Studio (Machine Creation Services) or Provisioning Services to create a catalog of linked clones.

Troubleshooting – Graphics

For Citrix Policies that control graphics codecs, see http://www.carlstalhood.com/citrix-policy-settings/#graphics

Citrix Blog post – Optimising the performance of HDX 3D Pro – Lessons from the field

From Citrix Discussions: To exclude applications from Citrix 3D rendering, create a REG_DWORD registry value “app.exe” with value 0 or a registry value “*” with value 0.

  • Both x86 and x64:
    • reg add hklm\software\citrix\vd3d\compatibility /v * /t REG_DWORD /f /d 0

Wildcards are not supported. The asterisk * here has a special meaning “all apps” but is not a traditional wildcard. To blacklist multiple apps e.g. both appa.exe and appb.exe must be done by creating a registry value for each app individually.

This is most problematic in Remote PC since most physical PCs have GPUs. I recently had to blacklist Internet Explorer to prevent lockup issues when switching back to physical.

Uninstall VDA

Uninstall the VDA from Programs and Features.

Then see CTX209255 VDA Cleanup Utility.

To run the VDA Cleanup Tool silently:

  1. Execute VDACleanupUtility.exe /silent /noreboot to suppress reboot.
  2. Once the VDACleanupUtility has finished executing, setup Auto logon for the current user.
  3. Reboot.
  4. After reboot, tool will launch automatically to continue Cleanup.

Another option is to delete CitrixVdaCleanup value under HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce. Then after reboot, run VDACleanupUtility.exe /silent /reboot to indicate that it’s running after the reboot.

Navigation

Citrix Director 1808 is newer than Director 7.18.

💡 = Recently Updated

Change Log

Director Licensing – Platinum Edition

Here’s the list of Director features that require Platinum Edition or Premium Edition licensing.

  • Up to a year’s worth of performance data that provides a comprehensive view of capacity trends
  • Application Probing
  • Alerting including SNMP integration
  • SCOM alerts
  • Desktop and server OS usage reporting
  • Create customized reports
  • Reboot warnings
  • NetScaler MAS integration – HDX Insight
  • Override control over roaming sessions

See Citrix Docs Feature compatibility matrix for a list of which Director feature came with each version, and the licensing Edition needed for each feature.

Install/Upgrade Director 1808 on Standalone Server

Current Release vs LTSR – Director 1808 is a Current Release, which is only supported for 6 months from the release date, and you are expected to upgrade it every 3-6 months. If you prefer a release with a longer support cycle, see Director 7.15 LTSR.

Install on Delivery Controller? – The Virtual Apps and Desktops Delivery Controller metainstaller has an option to install Director on the Delivery Controller machine. Or you can install Director on separate, dedicated machines.

  • If Director will connect to multiple sites/farms, then install Director on its own servers.
  • For small environments, it might be OK to install Director on the Delivery Controller machines. Otherwise, Director is usually installed on separate machines.

Director and Delivery Controller versions – There’s no point in upgrading to Director 1808 if your Delivery Controllers are not also 1808. Director will inform you if your Delivery Controllers are not the same version as Director.

Installation guidance – For Director installation guidance, see the following:

Scripted install – To install and configure Director using a script, see Dennis Span Citrix Director unattended installation with PowerShell.

Manual installation – To install Director manually:

  1. Start with running AutoSelect.exe from the Citrix Virtual Apps and Desktops 1808 ISO.
  2. In the Extend Deployment section, on the bottom left, click Citrix Director.
  3. In the Licensing Agreement page, select I have read, understand, and accept the terms, and click Next.
  4. In the Core Components page, click Next.
  5. In the Delivery Controller page, it will ask you for the location of one Delivery Controller in the farm. Only enter one Delivery Controller per farm. If you have multiple Director servers, each Director server can point to a different Delivery Controller in the farm.
    • From Citrix Docs: Director automatically discovers all other Delivery Controllers in the same Site and falls back to those other Delivery Controllers if the Controller you specified fails. Click Test Connection, and then click Add.
  6. You can optionally force SSL/TLS for the Monitoring service by following the instructions at Data Access Security at Citrix Developer Documentation. Also see CTX224433 Error: “Cannot Retrieve Data” on Citrix Director Dashboard After Securing OData Interface Through TLS.
  7. In the Features page, click Next.
  8. In the Firewall page, click Next.
  9. In the Summary page, click Install.
  10. A machine restart will probably be needed.
  11. After the restart, login.
    1. If you see a Locate ‘Citrix Virtual Apps and Desktops 7’ installation media window, don’t click anything.
    2. Mount the Citrix_Virtual_Apps_and_Desktops_7_1808_2.iso.
    3. Go back to the Locate ‘Citrix Virtual Apps and Desktops 7’ installation media window. On the left, expand This PC and click DVD Drive. Then click Select Folder.
    4. Installation will resume.
  12. In the Finish page, click Finish.
  13. In IIS Manager, go to Default Web Site > Director > Application Settings, find Service.AutoDiscoveryAddresses, and make sure it points to one Delivery Controller in the farm, and not to localhost. From Citrix Docs: Director automatically discovers all other Delivery Controllers in the same Site and falls back to those other Delivery Controllers if the Delivery Controller you specified fails.
  14. If you built multiple Director servers, use NetScaler ADC to load balance them.
  15. If you are upgrading Director, run C:\inetpub\wwwroot\Director\tools\DirectorConfig.exe /upgrade to complete the upgrade process.
  16. For info on the new monitoring features in Director, see Use Director below.

Director Default Webpage

From CTX223907 How to Make Director the Default Page within IIS: If Director is installed on a standalone server, do the following to set /Director as the default path.

  1. Open Notepad elevated (as administrator) and paste the following text: 
    <script type="text/javascript">
<!--
window.location="https://director.corp.com/Director";
// -->
</script>
  2. Adjust the window.location line to match your FQDN.
  3. Select File > Save As and browse to the IIS folder, by default C:\inetpub\wwwroot is the IIS folder.
  4. Select the Save as type to All types.
  5. Type a file name with an html extension, and select Save.
  6. Open IIS Manager.
  7. Select the SERVERNAME node (top-level), and double-click Default Document, as shown in the following screen shot:
  8. On the right, click Add…,
  9. Enter the file name of the .html file provided in Step 5.
  10. Ensure the .html file is located at the top of the list, as shown in the following screen shot:

Director Spinning Circle

If after login to Director the spinning circle doesn’t go away…

Do the following to fix it:

  1. Edit the file C:\inetpub\wwwroot\Director\web.config using an elevated text editor.
  2. Search for <serviceHostingEnvironment (line 273).
  3. Add the following attribute: 
    multipleSiteBindingsEnabled="true"

Also see CTX202564 Citrix Director Becomes Unresponsive after Submitting the Credentials when IIS X-Frame-Options is enabled

Director Domain Field

On the Director servers, locate and edit the ‘LogOn.aspx’ file. By default you can find it at C:\inetpub\wwwroot\Director\Logon.aspx

In line 450 you will have the following. To find the line, search for ID=”Domain”.

<asp:TextBox ID="Domain" runat="server" CssClass="text-box" onfocus="showIndicator(this);" onblur="hideIndicator(this);"></asp:TextBox>

In the ID=”Domain” element, insert a Text attribute and set it to your domain name. Don’t change or add any other attributes. Save the file.

<asp:TextBox ID="Domain" runat="server" Text="Corp" CssClass="text-box" onfocus="showIndicator(this);" onblur="hideIndicator(this);"></asp:TextBox>

This will prepopulate the domain field text box with your domain name and still allow the user to change it, if that should be required. Note: this only seems to work if Single Sign-on is disabled.

Citrix CTX227936 How to hide the domain from Director Logon Page:

  1. Edit the file C:\inetpub\wwwroot\Director\LogOn.aspx using an elevated text editor.
  2. Locate the tag which starts with: <asp:Label ID="DomainLabel"
  3. Immediately prior to that label, locate the tag: <div class='label eight'>
  4. Add the following before <div class=’label eight’>: <div style='display:none'>
  5. In between “</asp:Textbox> <br />” add the following: </div>

Director Tweaks

Session timeout

By default the idle time session limit of the Director is 245 min. If you wish to change the timeout, here is how to do it.

  1. Log on to the Director Server as an administrator
  2. Open the ‘IIS Manager’
  3. Browse to ‘SitesDefault Web SiteDirector’ in the left hand pane.
  4. Open ‘Session State’ in the right hand pane
  5. Change the ‘Time-out (in minutes)’ value under ‘Cookie Settings’
  6. Click ‘Apply’ in the Actions list

SSL Check

From http://euc.consulting/blog/citrix-desktop-director-2-1: If you are not securing Director with an SSL certificate you will get this error at the logon screen.

To stop this:

  1. Log on to the Director Server as an administrator
  2. Open the ‘IIS Manager’
  3. Browse to ‘SitesDefault Web SiteDirector’ in the left hand pane.
  4. Open ‘Application Settings’ in the right hand pane
  5. Set UI.EnableSslCheck to false.

Disable Activity Manager

From Disable the visibility of running applications in the Activity Manager in Advanced Configuration at Citrix Docs: By default, the Activity Manager in Director displays a list of all the running applications and the Windows description in the title bars of any open applications for the user’s session. This information can be viewed by all administrators that have access to the Activity Manager feature in Director. For Delegated Administrator roles, this includes Full administrator, Delivery Group administrator, and Help Desk Administrator.

To protect the privacy of users and the applications they are running, you can disable the Applications tab from listing running applications.

  • On the VDA, modify the registry key located at HKLM\Software\Citrix\Director\TaskManagerDataDisplayed. By default, the key is set to 1. Change the value to 0, which means the information will not be displayed in the Activity Manager.
  • On the server with Director installed, modify the setting that controls the visibility of running applications. By default, the value is true, which allows visibility of running applications in the Applications Change the value to false, which disables visibility. This option affects only the Activity Manager in Director, not the VDA. Modify the value of the following setting:
    UI.TaskManager.EnableApplications = false

Large Active Directory / Multiple Forests

From CTX133013 Desktop Director User Account Search Process is Slow or Fails: By default, all the Global Catalogs for the Active Directory Forest are searched using Lightweight Directory Access Protocol (LDAP). In a large Active Directory environment, this query can take some time or even time out.

If multiple forests, see Citrix Blog Post Using Citrix Director in a MultiForest Environment.

  1. In Information Server (IIS) Management, under the Desktop Director site, select Application Settings and add a new value called Connector.ActiveDirectory.ForestSearch. Set it to False. This disables searching any domain except the user’s domain and the server’s domain.
  2. To search more domains, add the searchable domain or domains in the Connector.ActiveDirectory.Domains field.

Site Groups

From Citrix Blog Post Citrix Director 7.6 Deep-Dive Part 4: Troubleshooting Machines:

If there are a large number of machines, the Director administrator can now configure site groups to perform machine search so that they can narrow down searching for the machine inside a site group. The site groups can be created on the Director server by running the configuration tool via command line by running the command:

C:\inetpub\wwwroot\Director\tools\DirectorConfig.exe /createsitegroups

Then provide a site group name and IP address of the delivery controller of the site to create the site group.

Director Configuration Script

Johan Greefkes at Script for configuring Director at Citrix Discussions was kind enough to provide a script that does the following:

  • Sets the Delivery Controllers that Director communicates with
  • Disables SSL Check
  • Sets Logon.aspx file to default to a domain name
  • Adds a footer that displays the name of the Director server

Director – Saved Filters

From Scott Osborne and Jarian Gibson at Citrix Discussions: In Director, you can create a filter and save it.

The saved filter is then accessible from the Filters menu structure.

The saved filters are stored on each Director server at C:\Inetpub\wwwroot\Director\UserData. Each user has their own saved filters. The saved filters are not replicated across Director servers.

You can instead configure multiple Director servers to store the filters on a shared UNC path: (h/t CTP Jarian Gibson)

  1. Create and share a folder (e.g. DirectorData).
  2. The Director server computer accounts need Modify permission to the share.
  3. On each Director server, run IIS Manager.
  4. Go to Sites > Default Web Site > Director. In the middle, double-click Application Settings.
  5. Change the Service.UserSettingsPath setting to the UNC path of the new share.
  6. Repeat this on other load balanced Director servers.

Director and HDX Insight

You can connect Director to NetScaler Management & Analytics System (NetScaler MAS) or Citrix Insight Center to add Network tabs to Director’s Trends and Machine Details views. Citrix Blog Post Configure Director with NetScaler Management & Analytics System (MAS).

Director Grooming

If Citrix Virtual Apps and Desktops is not Platinum Edition or Premium Edition, then all historical Director data is groomed at 30 days.

For Citrix Virtual Apps and Desktops Platinum Edition or Premium Edition, by default, most of the historical Director data is groomed at 90 days. This can be adjusted up to 367 days by running a PowerShell cmdlet.

  1. On a Delivery Controller, run PowerShell and run asnp Citrix.*

  2. Run Get-MonitorConfiguration to see the current grooming settings.
  3. Run Set-MonitorConfiguration to change the grooming settings.

More details on Monitor Service data aggregation and retention can be found at Data granularity and retention at Citrix Docs.

Director Single Sign-on

You can configure Director to support Integrated Windows Authentication (Single Sign-on). Note: there seem to be issues when not connecting from the local machine or when connecting through a load balancer.

  1. Run IIS Manager. You can launch it from Server Manager (Tools menu), or from the Start Menu, or by running inetmgr.
  2. On the left, expand Sites, expand Default Web Site, and click Director.
  3. In the middle, double-click Authentication in the IIS section.
  4. Right-click Windows Authentication, and Enable it.
  5. Right-click Anonymous Authentication, and Disable it.
  6. Pass-through auth won’t work from another computer until you set the http SPN for the Director server. See Director 7.7 Windows Authentication not working with NS LB at Citrix Discussions.
  7. If Director is not installed on a Controller, then you’ll need to configure Kerberos delegation.
  8. If you are load balancing Director then additional config is required. See Director 7.7 Windows Authentication not working with NS LB at Citrix Discussions for more info.
    1. The FQDN for Director load balancing should be different than the FQDN for StoreFront load balancing.
    2. Create an AD service account that will be used as the Director’s ApplicationPoolIdentity.
    3. Create SPN and link it to the service account. 
      setspn -S http/loadbalanced_URL domain\user
    4. Trust the user account for delegation to any service (Kerberos only) (trust the Director servers for delegation is not necessary in this case). You have to create the SPN before you can do this step.
    5. In IIS manager, on the Application Pools (Director), specify the Identity as user we have created in step 1.
    6. In IIS manager, expand Default Web Site, select Director, and open the Configuration Editor (bottom of the middle pane).
    7. Use the drop-down to navigate to the following section: system.webServer/security/authentication/windowsAuthentication
    8. Set useAppPoolCredentials = True, and useKernelMode = False. Click Apply on the top right.

  9. When you connect to Director you will be automatically logged in. You can change the login account by first logging off.
  10. Then change the drop-down to User credentials.

Director – Multiple Citrix Virtual Apps and Desktops Sites/Farms

  1. Run IIS Manager. You can launch it from Server Manager (Tools menu) or from the Start Menu, or by running inetmgr.
  2. On the left, expand Sites, expand Default Web Site, and click Director.
  3. In the middle pane, double-click Application Settings.
  4. Find the entry for Service.AutoDiscoveryAddresses, and double-click it.
  5. If Director is installed on a Controller, localhost should already be entered.
  6. Add a comma, and the NetBIOS name of one of the controllers in the 2nd Citrix Virtual Apps and Desktops Site (farm). Only enter one Delivery Controller name. If you have multiple Director servers, you can point each Director server to a different Delivery in the 2nd Citrix Virtual Apps and Desktops Site (farm).
    1. From Citrix Docs: Director automatically discovers all other Delivery Controllers in the same Site and falls back to those other Delivery Controllers if the Delivery Controller you specified fails.
    2. You can optionally force SSL/TLS for the Monitoring service by following the instructions at Data Access Security at Citrix Developer Documentation. Also see CTX224433 Error: “Cannot Retrieve Data” on Citrix Director Dashboard After Securing OData Interface Through TLS.

Director Process Monitoring

Director 7.11 and newer have Process Monitoring, which is detailed in Citrix Blog Post Citrix Director: CPU, Memory Usage and Process Information.

Process Monitoring is disabled by default. To enable it, configure the Enable process monitoring setting in a Citrix Policy. For Citrix Policies in a GPO, find this setting in the computer half of the GPO. Note: this setting could significantly increase the size of the Monitoring database.

Director Alerts and Notifications

Director supports alert conditions and email notifications. This feature requires Citrix Virtual Apps and Desktops to be licensed with Platinum or Premium Edition. See Citrix Blog Post Configuring & Managing Alerts and Notifications Using Director for more information.

Director – Custom Reports

In Director 7.12 and newer, in the Trends view, there’s a Custom Reports tab that guides you through creating a custom OData Query. This tab only appears if you have Citrix Virtual Apps and Desktops Platinum Edition or Premium Edition.

The Monitoring database contains more data than is exposed in Director. To view this data, the Monitoring service has an OData Data Feed that can be queried.

Use Director

The newer Director features usually require Delivery Controllers and VDAs to be at the same version or newer than Director. Director depends on the Monitoring Service that is built into the Delivery Controller. The Monitoring Service gathers data from the VDAs.

See Site Analytics at Citrix Docs.

See the various Troubleshoot topics at Citrix Docs.

New features in Director 1808 and newer:

  • Interactive Session drilldown – also in the Logon Duration panel, hover your mouse over the Interactive Session bars to see this phase broken down. More info at Diagnose user logon issues at Citrix Docs.

Requires Director 7.13, Controller 7.13, VDA 7.13, and Platinum Edition or Premium Edition licensing. See Citrix Blog Post Monitoring Idle Applications and Sessions in Citrix Director. See Troubleshoot applications at Citrix Docs.

If idle time column shows n/a, then you need to wait 10-15 minutes.

In Director 7.13 and newer, the Session Details panel can show if Enlightened Data Transport (EDT, aka HDX on UDP) is enabled in the user’s session. See Citrix Blog Post HDX Adaptive Transport Protocol Monitoring via Director.
