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.
