Have a win 2008 (not R2)std sever runing Terminal server.
It's on a Vmware ESXi host.
Lately Svchost.exe uses 50-60% CPU, so the server is always at 100%
In taskmanager , right-clicked service and chose Go to services.
Than showes Dcomlaunc and PlugPlay.
Have searched around and found a fix for Win 2008 R2: (http://support.microsoft.com/kb/2655998
1. not sure it applies since on this server it's at 50-60% all the time, and
2. it's not Win 2008 R2
Also found allot about disabeling enhanced audio (Vista problem mostly), but this is a terminal server without audio device installed.
