Windows 2003 TS and TrendMicro OfficeScan 8.5

Posted on

On a Windows Server 2003 Terminal server, if TrendMicro OfficeScan is installed, the following symptoms occur:

1. When users try to log onto the Windows 2003 Terminal Services, the system slows down or becomes unresponsive. Sometimes it hangs or times out. The logon or logoff can take an unexpected long time.

2. However, on the server, if we stop the Trend Micro Service, the system goes back to normal.  


Trend Micro has released a patch Scan Engine 8.510-1003, which resolves the issue.For more information, you may cilck the link below from TrendMicro Web site.

    We currently use Trend Micro on all of our notebooks and are thinking about using it for our terminal servers. We have about 80 users on terminal services.

    I had a couple of questions.
    Does it load a seperate instance of the client piece for each user that is logged on?
    Have you noticed any other server performance issues other then the one you addressed here?

    Thank you,
