We are running SBS 2003, and every Friday it seems to crash--usually during our backups. It is always accompanied by this error: The reason supplied by user WALLACE\Administrator for the last unexpected shutdown of this computer is: System Failure: Stop error Reason Code: 0x805000f Bug ID: Bugcheck String: 0x000000d1 (0x00000024, 0xd0000007, 0x00000000, 0xf74fbe02) Comment: 0x000000d1 (0x00000024, 0xd0000007, 0x00000000, 0xf74fbe02) For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. It seems to be a device driver as far as I can tell, but I have loaded new drivers for about every device that I thought would be associated with this error, and it continues to crash every weekend. The strangest part about this is that we don't run anything any differently on the weekend than we do during the week, yet it rarely crashed during the week. If anyone has any ideas, I would appreciate the help!
