Fixed issues 编辑

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:

  Data source unresponsive or reported an error. View Director Server event logs for further information. [LD1441]

• Citrix Director might show only a few table records, followed by an empty space. You can see the remaining records only after scrolling down the table. [LD1706]

Citrix Studio

• When you select Advanced for XenApp edition, you might not be able to create a new Amazon Web Services (AWS) host connection. [LD1988]

• 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 domainObjectSID attribute in the dbo.device table 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

• Attempts to delete a base disk image using Machine Creation Services (MCS) might fail. [LD2143]

• This fix addresses a memory leak issue that occurs in the Citrix High Availability Service when you restart a VDA. [LD1121]

• There might be a delay of several minutes when you restart a machine while using Amazon Web Services (AWS). [LD1220]

• The CPU usage of the Monitor database might be very high on the SQL Server. This issue degrades overall performance. [LD1478]

• The power action performed manually from the Citrix Studio, or any other scheduled power action, might fail when using Amazon Web Services (AWS). The issue occurs when you reset the virtual machines while the machine is powered on. [LD1548]

• Attempts to stop the Citrix Broker Service might fail. [LD1753]

• This fix addresses an issue in an underlying component. [LD1808]

• When you run the Citrix Scout report, the Citrix Analytics Service might exit unexpectedly and this error message appears:

  The Citrix Analytics service has stopped running. [LD1860]

• The catalog update might fail without displaying an error message or a progress bar. [LD1980]

• When you select Advanced for XenApp edition, you might not be able to create a new Amazon Web Services (AWS) host connection. [LD1988]

• Attempts to delete the virtual machines from a catalog might fail with the exception System.ArgumentNullException Value cannot be Null. [LD2014]

• When you navigate to Citrix Director > Trends > Capacity management > Server OS Usage, the Peak Concurrent Server OS Desktop Instances metric might show a session count that is beyond the actual count. The issue occurs when the Peak Concurrent Server OS Desktop Instances calculation counts a single session multiple times because of session reconnect. [LD2122]

• If you attempt to create a machine catalog using Machine Creation Services (MCS) in a VMware environment, catalog creation fails with the following error message:

  FailedToCreateImagePreparationVm [LD2158]

• Attempts to create or update the Machine Creation Services (MCS) catalogs on Microsoft Azure might fail with the following error message:

  Error, exception of type: “System.OutOfMemoryExceotion” [LD2160]

Linux VDA

Linux Virtual Delivery Agent 7.15 LTSR CU5 documentation provides specific information about the updates in this release.

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]

• There might be discrepancies in the logon duration time that Citrix Director records, compared to the event log data that VDAs provide. [LD1679]

• Profile Management does not cancel copy operations to the profile store after it fails to load a corrupt local profile NTUSER.DAT. Instead, Profile Management copies the corrupt registry hive to the profile store and overwrites the NTUSER.DAT file 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]

• The Citrix Desktop Service (BrokerAgent.exe) might exit unexpectedly and the following exception occurs until you restart the Citrix Profile Management Service:

  System_Management_Instrumentation_ni!WmiNative.WbemProvider.WmiNative.IWbemServices.CreateInstanceEnumAsync [LD2223]

Provisioning Services

Provisioning Services 7.15 LTSR CU5 provides specific information about the updates in this release.

StoreFront

• The Universal Print Server might cause the Print Spooler service to become unresponsive. [LC9341]

• Before you print a document, choose a printer from the list of available printers in the published desktop session’s print dialog box. There might be a delay until the printer starts printing the document. [LC9601]

• After installing a VDA, the printer ports under printer Properties might no longer appear on a mapped network printer. [LD0949]

• Attempts to print a document might be slow in some workflows. [LD1256]

• With the Universal print driver usage setting set to Use universal printing only, the client printers might not be auto-created in a session. [LD1395]

User Profile Management VDA

• 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]

VDA for Desktop OS

Keyboard

• When you change visual effects within a user session, the UserPreferencesMask value under the registry key HKEY_CURRENT_USER\Control Panel\Desktop might not be updated to a new value. [LD1827]

  To enable the fix, create the following registry key:

  HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook\AppInit_DLLs\UI Tweak\SystemPropertiesComputerName.exe

  Type: REG_DWORD

  Data: 1
