OK. Well, it was a good guess, you have to admit. Make sure your firmware on
everything is up to date - and I'd run Dell's online diagnostics and tape
drive testing utilities. I'd call their support for help with that. What you
have is most definitely a hardware related problem.

I've been struggling with a strange problem for the past few weeks.
It seems that every few days, my clients' SBS 2003 Standard server
freezes up while running the SBS backup. The only way to bring the
server back online is a hard reset. Because it freezes up, there is
nothing in the logs except for the unexpected shutdown. From
looking at the times, it always happens 1 3/4 hours into the
backup. It will also run fine for days. By looking at the
successful backup logs, this is about the time it finishes the data
backup and goes to do the System State and Exchange Store. I think
it has something to do with one of these.

Server Specs:
HP ML350
4 GB RAM
(2) RAID 1 Mirrors (C: 38GB for OS and D: 146GB for Data) SAS drives
Ultrium 448 SCSI Tape Drive - internal

Other than the tape drive, all equipment was new. The tape drive
was pulled from their other server and was working fine beforehand.
The SCSI termination appears to be okay. The entire setup ran fine
for over 2 months before the problems started.

I updated the driver and firmware for the tape drive but it did not
resolve anything. Today, I plan to install a USB drive temporarily
for the backups to eliminate the tape drive from the equation. I've
seen problems like this before due to heat but I don't think this is
the problem here. It literally happens at the same exact time. It
just doesn't happen every single day. It's about 2-3 times per
week. Has anyone run into a similar situation? We're pulling our hair
out
trying to figure this one out.

This is a hardware problem, and I'll put money on it that your tape
drive is hooked up to your RAID controller. This is a major no-no
.... get a dedicated SCSI controller for the tape drive.
