I have an SBS 2003 server that reboots at exactly the same time every two weeks.  I realize that this is obviously a scheduled process,  but I can't find it anywhere.  There is nothing under the scheduled events or nothing listed when I do an "AT" command.   I have noticed  that prior to the reboot the store.exe seems to be using about 50% cpu utillization and the RPCServ.exe is bumps up to about 30% and drops.

Very odd, but one thing to check is your UPS. Perhaps it does a scheduled self test, and if the battery is weak it could force the server to shut down.

Then there is the famous story of the server that rebooted every week at the same time. The tech stayed one night to actually watch the server to discover the cleaning staff reached around the corner of the server room, unplugged the server and plugged in the vacuum....every Wednesday night   :-)

Make sure your A/V is up to date.

If you've checked out the "cleaner plugging in the vacuum" scenario, I'd look at backup or AV scanning.  Is there a process involving one of these programs that runs every 2 weeks, or runs differently every other week?  It could be something like a conjunction of a backup process and an antivirus scanning process running at the same time.

Check the logs to see what tasks are running at that time. A/V is one culprit.

Also, make sure that any Volume Shadow Copy services that are set to run on a schedule do _not_ collide at that time as that will cause all kinds of funky behaviours including the behaviour you are seeing.

Can you zip and post the dump file from %windir%\MiniDump ?
