W2K Network Lockup Troubleshooting

By Kevin at Alexander Group ·
I have been working on an issue with a Windows 2000 network with W98 clients. Periodically, all network adapters lose connectivity. They simply can't see any other IP addresses. This state stays in effect for each computer until it is rebooted (ie the clients can see each other once rebooted, but not any unrebooted machines.) We have worked with Microsoft to vet our server settings. We have switched out the routing hardware. We have replaced NICs. We have analyzed the network and found the only issues to be some crosstalk and return loss on some of the cabling. Running network monitor when the lockup returns yields no signs of increased traffic.
The server has not locked up the couple of times we have been working on it when the lockup occurs, but it does lock up completely when we are not on it.
Any thoughts or advice would be appreciated.

W2K Network Lockup Troubleshooting

The issue ended up being bad RAM in the original server AND in the replacement. What a truly horrible combination of events. I appreciate all the thoughtful answers. Now I just have to make the client understand why I couldn't have foreseen this.
