I have multiple Windows 2000 Servers in a Co-Lo area, 1) Running 2K Server for Network Monitoring, and 2 running as DNS Servers. On Friday, the just started to reboot at random times. If it was one, it would be so alarming, but 3 different servers doing the same thing. First I though maybe it was a power thing, since the were attached to an older UPS. So I put in a new 1500 Smart UPS this afternoon. Now this evening when I logged in to them, they are still doing the same thing, but its not at the same time..One may shut down at 10, then one of the others at 10:30, then the other one at 11, completely random.
When I look in the event viewer, all it shows are messages from the restart. One message says the previous shutdown was unexpected, and the other ones are service starting mesages.
I haven't got a clue, I have never seen anything like it. I also have 2 other 2K Servers in the same place that are still running just fine...
Any help would be greatly appreciated..
