I have a Dell Poweredge 2600 server configured as a Windows2000 DC.
At irregular intervals the server kept powering off and had to be manually restarted. Dell have changed the motherboard, power distrubition board and the 2 power units. The server is now rebooting at irregular intervals.
It is on a UPS ring, no other machines on the UPS ring are affected. There are no error reports in the Event log - except for the odd error6008 - unexpected shutdown.
Any suggestions as to what may be causing this.
