How to tell why the Win2003 servers shut down?
I have about three 2008 servers and five 2003 servers. Two of 2003 servers (one is AD) got shut down by themselves last night sometime after about 11:30pm. I didn't notice until this morning. I successfully booted them back without any error or message in the Event Viewer. So I'm still puzzled about the reason of their shutdown. All other servers connecting to the same UPS are just running without interruption.
Can you help figure out?

I found only one file mini101008-01.dmp dated 10-10-2008 which obviously is not by the recent shutdown event.
Why could the two servers shut down by themselves within just 30 seconds away?

You wouldn't believe this...
It ends up to be the UPS. Here is the catch: there are multiple separate module in the UPS. The black-out just happened to be the module where my two 2003 servers plugged into, while others remained normal.
This is so rare.

Rare indeed, but it does happen. Glad you were able to find out the cause of the issue.
At least now you can troubleshoot these sort of problems if it does ever happen again! :)

What mostly surprises me is both shutdown time is just 30 seconds away. How could that happen?? I'm pretty sure that was not caused by Windows Update because it is configured to update manually instead of automatically for these two servers.
This really puzzles me. What do you think?
