Random Reboot - Windows Server 2003

We have a Win2k3 Server (Not SP1) running exchange 2k3 sp1 and Veritas Backup Exec 10. Over the last month I have noticed a few random reboots at random times. Seems to always be during the backup job. The following is the event log error:

Event Type:      Error
Event Source:      EventLog

User:            N/A
Computer:      AHMAIL1
Description:
The previous system shutdown at 1:11:04 AM on 5/5/2005 was unexpected.

It maybe overheat. If I were you, I would opened the case to improve the ventilation for 3 to 4 days. If the system still reboot, replace the PSU. The faulty hardware may be PSU, CPU, RAM or M/B. As PSU is the cheapest hardware component, replace it with bigger power supply will improve the stability of your PC.

In windows 2003, the only time the system shutsoff without deliberation is power.  Anyother shutdown including a crash or error message would result in an error log, and a confirmation of shutdown.  It could be that your power supply is being overpowered and tripping off. That is the first place I would look.  This does not matter if you are a UPS.

Do you find system dump event at the system event? If you can't find it, it is a hardware error.

No system dump in the system event.

I have moved the servers power supplies to a different circuit as recommended by eatmeimadanish.
I'll keep you posted as to the success or failure of this change.

The hardware problem includes faulty ram, cpu or m/b. If you have a huge Dr Watson log, the problem does not related to faulty PSU
Attach the following files at any webspace. I will study your log and dumps.
C:\Documents and Settings\All Users\Documents\DrWatson\user.dmp
C:\Documents and Settings\All Users\Documents\DrWatson\drwtsn32.log

Unfortunately neither of those files exist.

Only hardware error causing reboot does not have the log and dump.

Should I start with replacing the power supplies?

Wanted to give an update this week.

Moved the power supplies to different UPS. So far this week no random reboots.
Not sure if the original UPS were surging the power and causing the reboots.

Seems to be OK since I moved to a different UPS. No random reboots in the last week.

Hopefully the moderators will accept this request.
I'd like to give the max number of points to both eatmeimadanish and  cpc2004 for this issue.
There have been no random restarts on this system for two weeks.

I am not too concerned about points as much as helping and being fair with who gets credit.  I am glad you are up and running.
