I have a Windows SBS 2003 server that is constantly at maximum cpu usage. The System process is almost always pinging from 30% to 50%. It has all of its Windows Updates and has been restarted.
The server is actively using Exchange 2003, Blackberry enterprise, and WSUS. This coincidentally became a problem (or I noticed it) after one of our hard drives went bad. The problem is that it has continued even after replacing the hard drive and rebuilding the array.
What could be causing the System process to go this crazy? I have tried looking through Process Explorer for a pattern, but it does not appear to be a specific sub-process.
We have also run multiple anti-spyware/anti-malware scans and the Microsoft rootkit revealer and found nothing.
