lsass.exe terminated - restart of computer

[e1]

I've got several Server 2003 Std SP2 systems running AD that reboot
arbitrarily maybe once or twice a week. It seems to be getting more frequent
now too. I get the same event IDs every single time in the System and
Application event logs. I've run virus scans, used MBSA, ran the Malicious
Software Removal Tool, and installed hotfix 927342. Yet, despite everything
I've tried, searched endlessly on google for a solution, I cannot seem to
figure this problem out.

Here's some other info about my environment:

* 8 total DCs
* 6 sites
* 3 GCs (all of the GCs are in the same site - central datacenter) - the
other 5 DCs are have Universal group membership cacheing enabled
* 2 Exchange Servers - backend cluster and frontend OWA

Here's the events I'm seeing and it seems to be related to a problem with
lsass.exe:

Has anyone else seen or experienced this problem? I'd appreciate your help.

Every research I have done leading me the conclusion of some type of virus
infection forcing/LSAS to shutdown and resulting your DC to reboot. If none
if these remedies to current problem, I would get PS support on this

Hi, thanks for your reply. I will check the things you listed below. I'm
also running a network trace to see if there's anything connecting to the
server that would cause this. Do you think an infected PC on our network
could be causing this? I'm wondering if we have a PC that's infected,
connecting to the DC, and forcing it to reboot.

I believe we had symptoms like this at work a few years back with a Dell
PowerEdge. Turned out the problem was a bad power supply I believe. Once
we fixed that the errors and auto reboots went away so we assumed the
power supply was at fault.
