Windows SBS03 SP2 - The processor is experiencing a low level of idle time

Good morning, Experts.

I'm working on a server that I get a status message indicating that the processor's idle time is low.  I checked Task Manager and the Idle process hovers around 97-99%.  At the bottom of the Task Manager window, it's indicating somewhere between 40-60% usage, but there are no processes that are shown to be using the processor.  Even though the CPU usage is showing a good level of usage, the actual processes aren't reflecting that.

Any ideas?

A couple of follow-up questions...

1) Is this a single, dual or quad core/processor server?
2) How much memory is currently allocated to the server and swap?
3) Are you running MS SQL on the server?
4) Do you have an anti-virus software installed on the server?

1) 2 physical Xeon processors
2) 4gb physical memory, 4gb virtual memory
3) Yes, SQL is running
4) There isn't any antivirus on this server.

Thanks for the reply.

Most likely it's either the MS SQL or Microsoft Exchange that is causing the issues. I recommend running both the SBS & Exchange Best Practices Analyzer on the server to see any possible underlying issues and use its recommendations as well:

I ran both and the SBS one came up with several warning items.  I'm working on clearing those up.

Just an update.  I've almost finished making the changes recommended by the Best Practices Analyzers, but I'm still getting that message.
