svchost.exe taking all processor
We have a TS farm made of a few Windows Server 2008 SP2 machines. Ocassionally on some of them we observe an issue with svchost.exe which hosts services listed below. I tried to identify a service responsible for this behaviour by stopping them one by one but I get access denied on each of them. However I was able to view threads running within this process (using Process Explorer) and there is on with high CPU usage and CSwitchDelta. But I've got only its TID. How can I get more information about this thread? If I try to start any program (eg. Process Monitor) which requires elevation it fails with error The service did not respond to the start or control request in a timely fashion.
