Dhoward, I've been monitoring the system today and the "System" Process (NT Kernel & System) has been averaging between 3% and 15%. This is down from the 60% - 80% that it was consuming before. It's still a little weird that this is the only system we have with this issue, but for now it looks like the issue is fixed or at least much better. So I would say the hotfix did the trick. Let me know what you see if you end up applying the hotfix. It looks like they have 3 version of the fix for Windows 7/Windows 2008 R2 (X86, x64, ia64) I applied the x64. I didn't know 2008 R2 had a 32bit x86 version, I thought it was only 2008 that had that. So not sure what that is all about.

Dhoward, Well that's not good. I ran across an article talking about % Privileged Time. I started up Perf Mon on the system and added in % Privileged Time from the Object "Process". It's showing exactly what the processor is showing with the avg being 70-80%. I then found this hotfix from Microsoft An application stops responding, experiences low performance, or experiences high privileged CPU usage if many large I&#47O operations are performed in Windows 7 or Windows Server 2008 R2 . If have SP1 installed then this hotfix is included and it didn't fix the issue. We are not loading SP1 yet. I'm going to apply this tonight and see if it fixes the issue. Applied it on a non production system and it required a reboot. I'll let you know what happens.

dhoward how did your updates fair? Did it resolve the issue. I found this thread and I'm experiencing the same issue on a Windows 2008 R2 File server. No McAfee just Forefront installed.
