Process Explorer from SysInternals can give you breakout of the threads in that process that might ID which one is the CPU hog...

Also currently chasing down an independent potential cause as far as a certain switch that folks are on Mousa Hamad ________________________________ From: Steven M.

I am going to try and my best to fill in as many details as possible about our issue and see if I can get some feed back because I am really spinning my wheels on this problem: Basically at random intervals throughout the day folks will experience a "slow down" or "freeze up" in Outlook 2003 (all machines running XP Pro SP3/Office2003 SP3) and a telnet program that we use. We have several subnets and this is occurring across all of them at random times and to random people. When this behavior occurs svchost.exe will spike on the machines to 99%. It is impossible to recreate this problem and it is NOT happening to everyone. Like most companies there are certain people who are in these programs more than others so they may notice it more, but I am in Outlook all the time and have not had this behavior occur. I have researched and tried to pin point anything locally that might be causing this, I have done rebuilds of machines, tried running Outlook in Safe Mode all to no avail. Does anyone have any ideas or suggestions they are willing to throw my way? Thank you in advance and have a happy holiday weekend!! Mousa Hamad
