Fixed issues
Citrix Director
-
There are two domains present in the same Active Directory forest, a parent and a child domain. The user is added to a domain local group in the child domain, which automatically belongs to the XenDesktop Delivery group. When the administrator from the parent domain logs on to the Director, the dashboard displays a list of sessions. When the administrator attempts to view the session details, the following error message appears:
This user doesn’t have any running sessions or assigned desktops.
However, the administrator from the child domain does not encounter this issue. [LD0178]
-
On the Citrix Director console, when you send messages to multiple users who are filtered with Published Name for application instances, this error message might appear:
Message cannot be sent. Unexpected server error. View Director server event logs for further information. [LD1257]
-
Citrix Director might not display personalization data in the user data section, and this error message appears:
Unexpected server error. [LD1353]
-
In a multiple session environment, when you navigate to Filters > Sessions > All and log off from a session, the session logs off. When you select another session with the same user name for the second time and attempt to log off, this error message appears:

-
Attempts to delete the virtual machines from a catalog might fail with the exception System.ArgumentNullException Value cannot be Null. [LD2014]
-
The App-V packages deployed to VDAs might be incorrectly removed from the VDAs. This fix introduces a registry key under HKEY_LOCAL_MACHINE\Software\Citrix\AppV\Features. The key controls whether to enable or disable cleanup. By default, cleanup is disabled. [LD2025]
To enable it, add the following registry key:
HKEY_LOCAL_MACHINE\Software\Citrix\AppV\Features
Name: RedundantPackageCleanup
Type: REG_SZ
Data: True
-
Attempts to add machines to a machine catalog through Citrix Studio might fail with the following exception: Error Id: XDDS:081419B3. The issue occurs when the machine is added from a Provisioning Services device collection containing one or more target devices that contains a NULL
domainObjectSIDattribute in thedbo.devicetable of the Provisioning Services database. [LD2029]
Configuration Logging Services
- The site configuration test report might generate an error while resolving the user Security Identifiers (SID). The issue occurs when there is a check that verifies whether the Configuration Logging SID identities can be resolved from Active Directory. [LD1569]
Controller

Profile Management
-
When using Citrix Profile Management, Microsoft’s bug fix to delete the firewall rules that were created during the user logon under the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy might not work. The issue occurs because the Citrix Profile Management doesn’t call Microsoft’s standard API to delete the local profile. For more information about the fix, see the Microsoft Knowledge Base article KB4467684. [LD1074]
-
The files that you delete from a session might not be deleted from the UPM store. [LD1270]

NTUSER.DAT. Instead, Profile Management copies the corrupt registry hive to the profile store and overwrites theNTUSER.DATfile and its backup. [LD1816] -
Even though you add a registry path to the exclusion list, the registry path might still be saved. The issue occurs when there is a backslash (\) present at the end of the registry path. [LD1862]

- When you log on to a session, the user data might be deleted unexpectedly. The issue occurs when you change the file server address from path1 to path2 in the Citrix folder redirection path policy settings (for example, the Desktop path setting). But, path1 and path2 point to the same physical location. To prevent this issue, enable the Microsoft group policy setting Verify old and new Folder Redirection targets point to the same share before redirecting. For details, see the Description part of the Citrix folder redirection path policy settings. [LD1500]
