Try to identify any recent changes to the host. If it is ongoing it is often due to an updated driver or application filter.
Indeed if possible try to identify drivers that are out of date too and update them one at a time. Network and Video drivers are a common culprit because something else in the system (like antivirus) changes and the old drivers conflict.
I can't remember if SBS2011 has the Windows Update and BITS services. Temporarily stop them if they are running to see if they are related to the issue.
I suppose it's a production server and so checking if the problem goes away in Safe Mode might be difficult? :)

I like to use sysinternals Process Explorer to look deeper than Task manager can. See if http://superuser.com/questions/527401/troubleshoot-high-cpu-usage-by-the-system-process is helpful to you for troubleshooting. Lots in google searches about system.exe high cpu :)
