Fixed issues

The following issues have been fixed since 1808.2:

Citrix Director

  • Attempts to remove the user assignment from a desktop using Citrix Studio, PowerShell, or Citrix Director by a delegated administrator with a custom role might fail. The issue occurs when custom administrators have permissions to perform the operations on the Delivery Groups but do not have permissions on the Machine Catalogs. [LC8174]

  • The CPU usage of the w3wp.exe process might be very high on Citrix Director. [LC9222]

  • The ExportCsvDrilldownLimit value might not be applied for custom reports in Citrix Director. [LD0004]

  • Custom administrators might not be able to retrieve the session details from a VDA Version 7.15 when the Citrix Director is connected to the Delivery Controller Version 7.6. [LD0134]

Citrix Policy

  • Attempts to start App-V applications in single user admin mode from VDAs might fail. The issue occurs when the value of the ApplicationStartDetails registry key is empty or if the application details are missing from the registry key. [LC8798]

  • When you apply the loopback policy in merge mode to a VDA and add the StoreFront URL to a Delivery Group of the VDA in Citrix Studio, duplicate icons of published applications might appear. [LC8889]

  • When you run the Group Policy Results tool from the Group Policy Management console on a machine that is installed with VDA 7.15.2000, the following error message appears: An error occurred while generating report: Not Found. [LC9825]

  • The Citrix Print Manager service (cpsvc.exe) might exit unexpectedly. The issue occurs when there are residual entries in the printing registry key that is connected to a Group Policy Object (GPO). [LC9921]

  • The Group Policy engine might fail to insert all the values to the ApplicationStartDetails registry key. As a result, attempts to start App-V applications might fail. [LC9942]

  • When you attempt to back up a Group Policy and then import the Group Policy with the Group Policy Management Console (GPMC; gpmc.msc) Version 3.1.2, the GPMC might become unresponsive. The policy is imported nonetheless. [LD0173]

  • Attempts to use the Group Policy Management Console (GPMC; gpmc.msc) to copy a Group Policy Object (GPO) that contains Citrix Policy settings might fail and point to the GpmcInterop.dll. The Microsoft Management Console (MMC) exits unexpectedly. [LD0322]

Citrix Provisioning

Citrix Studio

  • Citrix Studio does not show the Start option. As a result, the Remote PC fails to power on. [LC9702]

  • In a large environment where many Application Groups are used, when you click the Applications tab in Studio, the session times out while fetching Get-BrokerApplicationGroup output. As a result, the following exception appears:

    Database could not be connected.

    Before throwing the exception, Studio becomes unresponsive while enumerating the Application Groups. [LD0012]

  • When you attempt to apply a Citrix policy to an Organizational Unit (OU) in Citrix Studio by clicking Browse in the Assign Policy window, the following error message might appear: An unknown error occurred.

    The following exception appears:

    Collection was modified; enumeration operation may not execute. [STUD-3847, LD0044]

  • When you start a dedicated desktop session, a logon failure might occur and the logoff process might get stuck. Citrix Studio shows the session as connected, but you cannot log off until you manually restart the machine. [LD0199]

  • The Citrix Studio hosting connection might give a warning message to use the HTTPS for XenServer hosting connections even though the HTTPS connections are not supported. [LD0210]

Controller

  • In a multi-type licensing scenario that is configured for Delivery Groups, an incorrect license type that is not configured for a Delivery Group might be checked out. [LC9086]

  • The Citrix High Availability Service (HighAvailabilityService.exe) memory usage might exceed 2 GB. [LC9446]

  • By default, the Amazon Web Services (AWS) ID of the Machine Creation Services (MCS) provisioned machine is non-persistent. This situation might cause the virtual machine power management actions to fail on the AWS.

    To configure the persistence of the AWS ID, use one of these options:

    • To enable the persistence of the AWS ID, set the Host connection’s Connection option field to CreateNewInstanceOnReset=false on the Advanced page.
    • To disable the persistence of the AWS ID, set the Host connection’s Connection option field to CreateNewInstanceOnReset=true on the Advanced page or delete the option.

    For the change to take effect, wait 10 seconds. [LC9960]

  • Attempts to create an application using the New-BrokerApplication command with the -AdminFolder parameter might not create the specified folder in certain scenarios. [LC9982]

  • Attempts to recreate the Local Host Cache with a Delivery Group name that contains special characters might fail with an Event ID 505. [LD0068]

  • When you upgrade a single Delivery Controller in a multiple Delivery Controller environment, the site test report might contain a mismatched database version. [LD0073]

  • Attempts to create a machine catalog on XenApp and XenDesktop Version 7.18 might fail. This failure might occur when you configure the Logging security to Prevent changes to the site configuration when the database is not available. [LD0133]

  • When using the PowerShell command get-brokericon -filename with the -servername parameter, the command returns an error message. [LD0324]

  • The Citrix Virtual Apps published applications might not enumerate intermittently. As a result, a blank screen appears after the session starts or the applications fail to start. The SQL server might experience high CPU usage and the SQL Monitor might show blocked and expensive processes. [LD0336]

  • When you manually restart the vCenter Server, the status of the power managed virtual machines that reside on the VMware hypervisor might become Unknown. The status becomes Unknown because the host connection is not available. After the vCenter Server restart completes, the virtual machine’s power state remains Unknown instead of restoring automatically. [LD0355]

  • HTML5 video redirection might activate in sessions that do not support HTML5 video redirection. [LC9935]

  • When processing a credit card transaction through a user device, the application and the user device can become unresponsive, or only a subset of data might be received. [LD0152]
