XenApp/XenDesktop 7.6 LTSR Cumulative Update 6 contains all fixes that were included in XenApp and XenDesktop 7.6 LTSR, Cumulative Update 1, Cumulative Update 2, Cumulative Update 3, Cumulative Update 4, and Cumulative Update 5, plus the following, new fixes:

Citrix Director 7.6.6000

  • Attempts to search for users when assigning them to machines might fail. The selected user is shown as null. [#LC8395]

Citrix Studio 7.6.6000

  • When upgrading a site using the XenApp license edition, the license edition might change from XenApp to XenDesktop unexpectedly. [LC6981]

Controller 7.6.6000

  • When upgrading a site using the XenApp license edition, the license edition might change from XenApp to XenDesktop unexpectedly. [LC6981]

  • The license features might be lost when the SQL server that is configured for Always On availability is restarted. [LC8449]

  • Image deployment might fail on XenDesktop 7.6. The issue occurs when the refresh commands that are sent from the Delivery Controller to Hyper-V causes an overload resulting in a timeout. [LC8639]

  • When you attempt to create or update a machine catalog with virtual machines that use the upgraded or imported distributed port group, the following error message might appear: Exception…Current node not found…type = ‘network’ [LC8657]

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

Provisioning Services 7.6.7

Console Issues

  • When you log on to the Provisioning Services Console using a different domain account, you might not be able to access the farm. This error message appears:

    “The domain/user does not have access to the Farm.” [LC8150] 

  • The Provisioning Services Console and Configuration wizard might be slow when running in a complex Active Directory environment. As a result, the Provisioning Services Console times out. By using this enhancement, instead of searching for all groups in all domains, you can search in preferred domains. You can then stop the search if you find the correct group. The following registry can be set to use different search options:
    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ProvisioningServices Name: DomainSelectOption Type: DWORD Value: Set the following values (in decimal) for different search approach 0 = Approach-0 (default) Search in user domain and PVS Admin groups’ domains (and other whitelisted domains if configured). 1 = Approach-1. Search with Approach-0, followed by other trusted domains of the user’s domain. 2 = Obsolete 3 = Search with Approach-0, the groups found are further enumerated over the parent domains. Used for a special Active Directory environment. 4 = Search with Approach-1, the groups found are further enumerated over the parent domains. Used for a special Active Directory environment. 5 = Approach-2. “One-step” search using “User” attribute in user domain and PVS Admin groups’ domains (and other whitelisted domains if configured). Used for a special Active Directory environment. 6 = Search with Approach-2, followed by other trusted domains of the user’s domain. [LC9065]

  • The default Active Directory search option might not be able to find the Provisioning Services administrator membership for certain users in a special Active Directory environment. This issue is related to how the group membership is associated through groups over the parent and child domains. [LC9800]

Server Issues

  • When you log on to the Provisioning Services Console using a different domain account, you might not be able to access the farm. This error message appears:

    “The domain/user does not have access to the Farm.” [LC8150]

Used for a special Active Directory environment. 6 = Search with Approach-2, followed by other trusted domains of the user’s domain. [LC9065]

  • When you merge two or more vDisks at the same time, the MgmtDaemon.exe process might exit unexpectedly. [LC9123]

  • The default Active Directory search option might not be able to find the Provisioning Services administrator membership for certain users in a special Active Directory environment. This issue is related to how the group membership is associated through groups over the parent and child domains. [LC9800]

Target Device Issues

  • Target devices might become unresponsive. [LC8897]

StoreFront 3.0.6000.1

  • Authentication failure might occur on the StoreFront servers. The issue occurs because of TCP dynamic port exhaustion. [LC8795]

  • On the non-English version of the Microsoft Windows operating system, the DetectReceiver string might fail to appear on the button on the StoreFront webpage. [LC9713]

VDA for Desktop OS 7.6.6000

Keyboard 

  • When you start an application on an Android device and you are in the text field, the keyboard might not appear automatically. Also, you must always touch the keyboard button for opening or closing. [LC8936]

Session/Connection 

  • Disabling Citrix Hooks might fail to take effect when several executables are added to ExcludedImageNames under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook. [LC8614]

  • Inconsistent mouse movement might occur in a multi-monitor environment using H configuration. You start a Microsoft Skype for Business session and start sharing the screen with the other user. The Citrix graphic driver receives an incorrect mouse location from the operating system.

    To enable the fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Name: DisableAppendMouse Value: DWORD Type: 00000001

    However, when you use the HDX session after setting the registry key, certain features that programmatically set the mouse pointer location might not work as expected. The features are:

    • Mouse Snap To feature.
    • The capability to synchronize mouse location between users with GotoMeeting screen sharing.
    • The capability to synchronize mouse location between users with Skype for Business screen sharing. [LC8976]
       
  • When you attempt to access a mapped client drive in a session and you don’t respond to a Citrix Workspace Security Warning dialog box, the other user’s session might become unresponsive. [LC9070]

  • The Citrix Audio Service might exit unexpectedly and then restart again. When you reconnect to the same session from the second end point (thin client), the new devices are not mapped correctly to the session. [LC9381]

System Exceptions 

  • Servers might experience a fatal exception, displaying a blue screen, on picadm.sys with bugcheck code 0x22. [LC6177]

  • This fix addresses a memory issue with the wdica.sys file that can cause servers to exit unexpectedly. [LC7666]

  • Servers might experience a fatal exception on picadm.sys and display a blue screen with bug check code 0x22 (FILE_SYSTEM). [LC7726]

  • Servers might experience a fatal exception on vdtw30.dll and display a blue screen with stop code SYSTEM_SERVICE_EXCEPTION (3b). [LC8087]

  • Servers might experience a fatal exception on picadm.sys and display a blue screen with bug check code 0x000000D1(DRIVER_IRQL_NOT_LESS_OR_EQUAL). [LC8830]

  • The VDA for Server OS might experience a fatal exception on wdica.sys and display a blue screen. [LC9695]

VDA for Server OS 7.6.6000

Keyboard 

  • When you start an application on an Android device and you are in the text field, the keyboard might not appear automatically. Also, you must always touch the keyboard button for opening or closing. [LC8936]

Server/Site Administration 

  • The following error message might appear for child domain users while launching an application through Web Interface or StoreFront:

    “You have not been granted access to this published application.” [LC7566]

Session/Connection 

  • Disabling Citrix Hooks might fail to take effect when several executables are added to ExcludedImageNames under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook. [LC8614]

  • A spurious XenApp session might be created on a VDA for Server OS when a Remote Desktop session disconnects and reconnects. [LC8706]

  • After upgrading to XenApp 7.6 Long Term Service Release (LTSR) Cumulative Update 4, there might be a five-second delay when you log on to a published application. [LC8894]

  • Inconsistent mouse movement might occur in a multi-monitor environment using H configuration. You start a Microsoft Skype for Business session and start sharing the screen with the other user. The Citrix graphic driver receives an incorrect mouse location from the operating system.

    To enable the fix, set the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Name: DisableAppendMouse Value: DWORD Type: 00000001

  • The VDA for Server OS might experience a fatal exception on wdica.sys and display a blue screen. [LC9695]

User Experience 

  • On the VDA for Server OS, the mouse cursor might disappear from the session. This issue occurs when the cursor changes to the Text Select cursor and the background color is the same as the color of the Text Select cursor. The default background color in Microsoft Windows for editable areas is white, while the default Text Select cursor color is also white. As a result, the cursor might no longer be visible. [LC8807]

  • When you adjust the screen resolution display to Medium or Larger, two mouse pointers might appear that create a blurry pointer experience. The issue occurs when the cursor is rendered on the VDA side, instead of Citrix Workspace side. [LC9373]
