Hi

are there any services or jobs starting at the time of the problem?

eg: backup starts=>server reboots

anything to see in the IML (eg ASR detected?)

It could be a runaway process. Do you have any printers installed on this server?

I have seen this on a number of occasions and have found that it could be due to:

- incorrect memory configuration
- failing peripheral card eg. Remote Insight Board
- poorly configured system
- incompatability between the HAL and the operating system
- Compaq system drivers

These are often very dificult to track down, however I have found that by going back to a the factory configuration ie. delivered state, often helps to isolate the problem

The server is blue-screening (since Insight Manager is not detecting an ASR event) and you have set the server to reboot automatically on a STOP event. Change the settings in the System Control Panel to not have the server reboot and you will see the blue screen message and be able to troubleshoot.

We've been experiencing the same problem of server rebooting abnormally. There are no specific patterns and the Event viewer shows only that the Server was unexpectedly shutdown. What puzzles all of us are , we replaced already all the parts, one by one except for the casing. But the problem still persists.

Any suggestions or ideas?

HI guys,

There is some good pointers here already, let me add a few.

If nothing in the loggs, and only thing you can find is an unexpected shutdown, consider:
UPS - Check the UPS log, remove UPS,
Check power.
Check that the server is not in too warm a room (id expect a sensor to indicate temperature, and voltage as well, but it can't hurt.

For the server where you think all parts have been replaced, really check to eliminate stupid things like a broken front panel and the harddrive.

If there is a Blue Screen, try Bluesave to capture it, and read technet MS Q articles to figure those ones out.

We had a bad keyboard monitor switch. If the server loses the connection, ASR would assume a hardware failure and begin its countdown to restart the server. We had 4 servers lose the connection at once and 3 rebooted simultaneously.
