Windows 2000 Domain Controller reboots on logins

We have a 2000 DC (SP4 - all current critical updates applied) that reboots during user logins in the morning. As far as we can tell, the reboots occur when multiple logins attempt to take place within a 5 - 10 minute period. Number of users is approximately 15; the DC is in a site of its own; the DC holds the roaming profiles for the users, as well as the printers.
After the server reboots, we have the users login one at a time with no problems.
This server did have an issue with rebooting itself on occasion before we discovered there was a problem with the system board - the board was replaced a couple of months ago and the problem was resolved -  until last week when we noticed the login reboot problem. In other words, we're really not suspecting the replacement board as the culprit this time due to the fact the reboots occur during logins only.
We've inspected the logs, and nothing appears to be a clear indicator as to the problem......we are going to swap this board out today or tomorrow to at least eliminate it as the problem once again.......any input would be greatly appreciated on this one.

When you replaced the system board, did you get new memory as well?  Black screens and reboots are generally hardware problems.  Blue screens are mainly software/driver problems.  Well, both statements are from my own experience that is...

Anyway, if this server is a name brand like Dell or HP, they probably have diagnostic tools either built-in or available via download.  I highly recommend you run them to test the memory and the rest of the system.

Here are two other tools to test memory:

http://www.memtest86.com/
http://www.mersenne.org/freesoft.htm

The second link is a prime number search program.  It has a torture test mode that can stress memory.  Let that run a while (maybe an hour or two, longer if you can) and see if it continues without errors.  This program is great for unveiling memory issues.

Thanks masterbaker....as stated, we will swap the board tonite and see how it goes tomorrow......the memory issue could be valid.
Unfortunately, it's an off-brand machine-----the system board has no manufacturer id on it, but we will look into the links you provided.
I'll post tomorrow with the result(s) of our action(s).....thanks again !!

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!
