W2K Suddenly Reboot Loop at Startup

[Guest]

I am working with a number of Windows 2000 PC's that suddenly are getting
into a rebooting loop at startup. The computer will power up, the Windows
splash screen will appear and the bar accross the bottom will fil completely.
Then it gets an "Unexpected Kernel Mode Trap" error message at a Blue screen
and then does a dump of physical memory. I've heard that this could be
caused by a recent Windows update provision. Any insights on what this is
and how to fix it would be appreciated.

Extra notes.
I have been able to boot successfully to Safe Mode.
I have rerun W2K SP4 and then it will boot up once and then fall back into
looping at reboot again.

Run msconfig.exe (http://www.svrops.com/svrops/dwnldoth.htm)
and disable all tasks under the Startup tab. See if the problem
persists. If it does not, restore the startup tasks 2 or 3 at a time
until you can isolate the culprit.

Also you may want to check your startup and recovery options and uncheck
reboot on error. If a service or something similar is causing an error the
system may reboot and go into a loop because the same service has an issue.
I found that by going into safe mode, you can then get back into the system
because the service is not running. My issue was with the UPS option.

Just a thought but perhaps it may help
