We are running Win 2000 server (TS installed) on Dell 2550 servers. These are clean installs and fully service packed. However they are doing unexpected reboots with nothing being written into the event log.This is affecting about 3 servers in different rack with different power sources to different UPS's. Has anybody come across this problem with W2K Server ????

Even though your servers are Dell, try to find out forced hardware. May be your power suply in the box of the computer are not so good. The Voltage are out of range - 12V may be 11V, 5V amy be 4V and etc. Mesure them for a long time. Hacker's attacks can do that. Try to change the IP addresses of the three servers and the old IPs can be assigned to a test computers.

I have found if you are running TS and PC Anywhere 9x that TS servers will have unexpected reboots with nothing being written into the event log. One way to eliminate this problem is by disabling one or the other remote program and sticking with theother.

Well,

after your server came back, does it write a eventlog error saying that a unexpected error ocurred? My WTS server also crashes once in a while, and i found out that the reason were outdated drivers. It gave me a blue screen out of nowhere, then it booted, and came back again.

See if the server is configured in order to automatically reboot after a crash (or BSOD). If it is marked, every time you get a blue screen in Windows 2000 it will boot by itself.

hope this helps...
