One of my servers is missbehaving!

W2K advanced server
SP 4
SQL Server 2000 SP3a

Occassionally it runs like a dog and I get periodic timeouts from my ASP applications (IIS is running on a separate box), which I am looking into...

BUT... what worries me is that I when I use "Task Manager" to have a look at what my server is up to I get different results in the "Performance" and "Processes" tabs

In the Performance tab the graph is reporting that the CPU is running at a constant 70-80% (peaking to 100% when it hits my slow T-SQL code :-(

If I look in the Processes tab to see what is taking all the CPU time (to make sure it is sql and not some rogue process) the Process lists reports that the CPU is basically 80 - 99% idle.

Sql server occassionally pops into the list.

In summary :
performance graph says CPU is constantatly loaded
process tab says CPU is basically idle



Which one is lying to me and how/why?

Any suggestions would be appreciated as I find this a little worrying!

(I have tried a quick "tlist" but cant see anything reported in that task list that isnt in the Task Mananger list)

Help!
