Server randomly rebooting due to bugcheck

Hi there,
I have a SBS2003 SP1 server which reboots at various times of day and shows
this entry in the event log:
The reason supplied by user xxxxx\Administrator for the last unexpected
shutdown of this computer is: System Failure: Stop error
Reason Code: 0x805000f
Bug ID:
Bugcheck String: 0x000000f4 (0x00000003, 0x89f041f0, 0x89f04354, 0x8094b734)
Comment: 0x000000f4 (0x00000003, 0x89f041f0, 0x89f04354, 0x8094b734)
For more information, see Help and Support Center at

To my knowledge nothing has changed in the time it has been happening.
Sometimes it also BSOD's when rebooting with an error:
"Process thread crucial to system operation has unexpectedly exited or been
terminated - restart your computer again & if this message appears again
contact your support company"
I have run the Microsoft debugger tool as detailed on Petergal's SBS blog
which produced the following output:

So then I searched around for the csrss.exe which I find "Csrss.exe is a
Microsoft client server runtime which generates worker threads for client
requests" and some references to virus/trojan activity but a virus scan on
the file comes up clean.
Any suggestions please?
TIA
Andy.
