You are correct. This server problem has been around for months. The consultant's "sniffer" laptop didn't reveal anything either.


>To be fair, these problems can be hard to track down. The first thing to check is the server's System Event Log. If the server is spontaneously rebooting there are 2 possibilities:

This is usually not due to intermittent hardware failure, you typically address this with updates to the latest W2K service pack and patches, and updates to the latest available hardware drivers (preferably Windows-certified or manufacturer reference drivers, especially for video). It may also be worthwhile looking for updated firmware (e.g. BIOSs) for the Dell motherboard, optical drives etc. if available.

These are usually due to hardware issues of some kind - can be as simple as poor quality power (does the server have a good-quality UPS?) or something subtle like flaky RAM, network card etc. Because these hardware issues are intermittent they are tough to track down. Dell has good hardware diagnostics for most of their systems; there are 3rd party and free ones (like MemTest86, google for links). You may need to run these tests for extended periods (e.g. overnight) to get an intermittent error to show up.

Hey, these are great tips Al, I'll work my way through them. Thanks so much.
