[Guest]

I have this situation on many laptops with windows 2000 SP4. All these
laptops are up to date with MS patches.

This system is shutting down. Please save all work in progress and log off.

AUTHORITY\SYSTEM. Time before shutdown: 00:04:59 Message: System Shutdown

I have a vague recollection that a certain virus used to
do this. Get a second opinion and scan your machine
from here:

www.antivirus.com ("free online scan").

You might also have a joker in the business who has
administrative access to all PCs and who shuts down
your machines remotely, with a time delay of 5 minutes.
See if the shutdown happens when the machine is
disconnected from the network, and don't forget to
check your scheduled tasks in c:\windows\tasks.

I already scan all laptops that have this problem, and didn't found any virus.
Is not W32.Blaster.Worm virus.

All these laptop are not in the network, so, no jocker ...

Thank you

Did you scan them with an independent scanner as
I suggested? Did you check your scheduled tasks?

I have a very similar problem with Windows2000 Server SP4, it keeps
re-booting randomly, every 2 to 4 days, only once 2 times in 2 hours. ITs a
fresh install, not connected tot he network or internet, so it can not be a
virus, but I scanned anyway for blaster and of course its clean. Tempature
and volatge is all ok ( used probe ) and tested memory and hard disks, all
ok. Power supply is 500 watts.
I have up to SP4, but no patches after that yet. I have been on this problem
for 2 weeks now, and seeing a gew posts with very similar descriptions, but
no solutions or ways to pinpoint the problem.
