Important Note(s) about This Release

• Caution! Installing this hotfix can inadvertently remove the Citrix Licensing component, if present, from the system. To prevent this issue, make sure to install Hotfix XA600W2K8R2X64060, available as Knowledge Center article CTX129224, before installing this and any subsequent hotfixes on systems running Citrix XenApp 6 for Windows Server 2008 R2. [#245185]
• Important: Installing this hotfix over an ICA session is not supported but you can install it through a remote desktop session using an administrator account.
• Installing this hotfix causes the ICA Session performance monitor counter to be removed. As a result, HDX Monitor for XenApp and some EdgeSight user session monitoring cannot find and report on that counter. To prevent this issue, make sure to install Hotfix XA600W2K8R2X64023 or its replacement before installing this and any subsequent hotfixes on systems running Citrix XenApp 6 for Windows Server 2008 R2. [#248473]
• Caution! This hotfix may require you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, see Citrix eDocs, the Citrix Product Documentation Library.

New Fixes in This Release

1. Upon server restart with configuration logging enabled, the IMA Service can take an unspecified amount of time to start.

   [From XA600W2K8R2X64048][#221158]

2. Attempts to launch an application, from the Web Interface using Active Directory Federation Services (ADFS) can fail and the following error message appears:

   "An error occurred while making the requested connection."

   [From XA600W2K8R2X64048][#228190]

3. A WSXICA 9 error can occur, causing users to no longer be able to connect to any applications. The following error message appears:

   "The description for Event ID 9 from source wsxica cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer."

   [From XA600W2K8R2X64048][#240438]

4. Provisioned XenApp servers refuse to accept connections if they are restarted while the license server is unavailable. The issue occurs because the license server cache file, MPS-WSXICA_MPS-WSXICA.ini, is saved in the %systemroot%\Program Files\Citrix folder, which might be unavailable when the server image shuts down.

   This fix allows you to save the license server cache file in a shared network location - a location separate from the XenApp server image - so that the file is available even when the server image shuts down. If you save the file in a location away from the server image, you must set the following registry key to point to the cache file location:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Install
   Name: LSWSXICALocation
   Type: REG_SZ
   Data: <network location of license server cache file>

   Note: You must restart the server after this registry edit in order for the license file to be cached.

   [From XA600W2K8R2X64048][#242177]

5. The Wfshell.exe process fails Microsoft's Application Verifier Handles test after a server restart.

   [From XA600W2K8R2X64048][#246596]

6. When logged on to a XenApp 6 Fundamentals Edition Web Interface site as an anonymous user, the user can successfully launch applications without being prompted for credentials.

   [From XA600W2K8R2X64048][#250740]

7. The Remote Desktop Licensing Manager displays the client name as "Unknown" for the Terminal Services Client Access Licenses (TSCALs) issued.

   [From XA600W2K8R2X64048][#251083]

8. The ICA Listener can utilize up to 100 percent of the CPU, causing servers to refuse connections.

   [From XA600W2K8R2X64048][#254787]

9. COM port redirection can fail with the following error message:

   "System error 66: The network resource type is not correct."

   [From XA600W2K8R2X64048][#256475]

10. This fix addresses the following issue:

    • Users might get directed to servers scheduled for restart and with logons disabled
    • Servers scheduled for restart and with logons disabled are listed when running the qfarm /load command

    [From XA600W2K8R2X64048][#259617]

11. When launching an RDP session from within a XenApp 6 session, the Shift Key might intermittently fail.

    [From XA600W2K8R2X64048][#260161]

12. After changing a server's IP address, connection attempts can fail.

    [From XA600W2K8R2X64048][#LA0019]

Fixes from Replaced Hotfixes

1. Terminal Services RemoteApps fail to launch from XenApp servers.

   [From XA600W2K8R2X64001][#231386]

2. When connecting to a server running Windows Server 2008 R2 with Service Pack 1, Terminal Services can exit unexpectedly. This causes users to experience a black screen during logon and the logon process fails to complete.

   [From XA600W2K8R2X64001][#232329]

3. Attempts to log on to a server with a user name that exceeds 19 characters in length fail and can cause the Winlogon.exe process on the server to exit unexpectedly. This fix adds support for user names up to 255 characters long.

   [From XA600W2K8R2X64001][#233858]

4. Attempts to connect to a XenApp 6 server from a Wyse terminal configured for smart card single sign-on fail.

   [From XA600W2K8R2X64011][#242752]

5. Connections from WinCE clients can get randomly dropped before the server logon screen appears.

   [From XA600W2K8R2X64013][#230540]

6. The CPU consumption of the CitrixCseEngine.exe process can spike unexpectedly and cause logon delays.

   [From XA600W2K8R2X64016][#240091]

7. Attempts to launch a published application that resides on a mapped network drive rather than on a XenApp server fail. When trying to connect to the application from the Web Interface, the following error message appears:

   "An error occurred trying to establish the connection."

   The issue is caused by an internal application installation check. To suppress the application installation check and prevent the issue from occurring, you must set the following registry key:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\IMA
   Name: DisableAppInstallCheck
   Type: REG_DWORD
   Data: 1 (allow published applications to reside on mapped network drives); 0 (do not allow published applications to reside on mapped network drives)

   Note: This issue does not occur in other versions of XenApp and Presentation Server. For related information, see Knowledge Center article CTX125104.

   [From XA600W2K8R2X64016][#242170]

8. Attempts to log on to a XenApp 6 server using Version 7 or earlier of the clients can cause svchost.exe to exit unexpectedly. As a result, further connection attempts to the server fail until it is restarted.

   [From XA600W2K8R2X64026][#237503]

9. Servers can experience a svchost.exe exception on termserv.exe and as a result become unresponsive.

   [From XA600W2K8R2X64030][#238866]

10. wfica32.exe might get initialized within a desktop session during disconnect or logoff of a pass-through session. This can cause the session to reconnect to itself and in the process lock out the user. This fix requires you to install both a server and a client-side hotfix that contains Fix #231831. If, after applying both hotfixes, you continue to observe the issue, create the following server-side registry key to resolve the issue:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client
    Name: CheckWfShellForPassThru
    Type: REG_DWORD
    Data: 1

    [From XA600W2K8R2X64040][#231831]

11. Winlogon.exe can exit unexpectedly when launching a published application. The issue occurs when the commandline, including parameters, exceeds 200 characters. This fix addresses the issue for commandline parameters that do not exceed 255 characters in length. For instructions on passing longer parameters, see eDocs topic LongCommandLine2.

    [From XA600W2K8R2X64040][#236631]

12. If you install XenApp 6 for Windows Server 2008 R2 without configuring it, the IMA Service fails to update CtxSta.config upon reboot if the XML port is set for "Sharing" with IIS.

    [From XA600W2K8R2X64040][#244230]

13. Restarting Branch Repeater while there are active server sessions can cause the XenApp server to experience a fatal exception, displaying a blue screen.

    [From XA600W2K8R2X64040][#244759]

14. Terminating a shadowed session from the Delivery Services Console using a key combination can cause users to loose keyboard and mouse control of their session.

    [From XA600W2K8R2X64040][#248234]

15. Attempts to connect to a server can fail. The issue occurs when attempting to connect to a server with multiple network adapters if an adapter that does not route clients is set to the lowest priority.

    [From XA600W2K8R2X64040][#250909]
