Hi Alvin,
Thank you for using Microsoft Technical Support Newsgroups.
Disconnect the network cable. If the CPU utilization decreases, there could
be a network hardware problem.
If network hardware has been ruled out, you can track down the thread ID and
the load address of that thread using perfmon, pviewer, and pstat. You can
then determine if a driver is causing the high CPU time:
1. Start performance monitor and make sure you are in chart view (realtime).
2. Hit the plus sign, select the thread object, and counter % processor
time.
3. Under instance, add all of the system threads to the chart.
4. Look for the thread that is taking all of the CPU time, there will be a
lot of them.
5. Once you find the thread, get the instance number from the bottom of
perfmon where it displays the counter.
6. Start pviewer.exe, this is from the resource kit.
7. In pviewer, under process, select the system process. Find the thread ID
that matches the instance number from perfmon under Threads.
8. Get the start address under thread information.
9. Run pstat.exe with the command "pstat > pstat.txt". Look at the bottom
of the pstat.txt, match up Load Addr with the start address you found from
pviewer.
If you can't find it just search the whole file for the start address. If
you get a match, this is the driver that is causing the problem. You will
need to find out what that driver is and either replace, upgrade or disable
it. If you do not get an exact match, then look for the closest driver
match within the address range that you determined in the previous steps.
Once again, thank you for using the newsgroups.
