  • 1.  Symantec Endpoint - Citrix Notification Tray Session Issue

    Posted Aug 08, 2016 06:43 AM

    Hi all,

    I've been rolling out Symantec 12.1.6 to most of our servers / clients and have come across an issue with regards to Citrix sessions.

    What should happen (Before Install):

    The users opens the Citrix application. The user uses the application and once they exit the application, it ended the session. 

    What is now happening (After Install):

    The users opens the Citrix application. The user uses the application and once they exit the application, the session remains.

    In Citrix connection center, you can see that it is the Notification tray icon that is keeping it open. I've read up on the issue and it gave me two solutions. (See Proposed solutions below for more detail).

    • Citrix - Seamless flags
    • Symantec - Disable SmcGui

    Both these solutions have not worked. I was wondering if anyone could help me please.

     

    Proposed solutions

     

    Citrix Possible Solution:

     

    Seamless Configuration Settings

    http://support.citrix.com/article/CTX101644&searchID=26517783

     

    I add a registry entry on my xenapp servers

     

    Registry Key: HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Citrix/wfshell/TWI

    Value Name: SeamlessFlags

    Value Type: REG_DWORD

     

    DISABLE SYSTRAY AGENT

    Value: 0x20

     

     

    Or Symantec Possible Solution:

     

    Upgrade to Symantec Endpoint Protection 11.0 Maintenance Release 3 or newer.

     

    In addition to upgrading, SmcGui must be disabled (to avoid multiple instances of that process and the SEP tray icon) by setting the following DWORD registry value on the Terminal Server:

    HKLM\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC\LaunchSmcGui = 0

    Have you reviewed and implemented Symantec's best practices for this? See here: http://www.symantec.com/docs/TECH91070

    Hi, 

    Thank you for the replies. After further troubleshooting I resolved the issue.

     

    Path: HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\CITRIX\WFSHELL\TWI

     

    Added: SeamlessFlags, REG_DWORD, Value:4120

    Edited: LogoffCheckSysModules. [Values: ccSvcHst.exe,ccSvcHst.exe*32]

     

    This resolved the issue. The users have to fully logoff their session before it starts working. :)
