Windows Server falling off the network
So this is one of the weirder problems I've encountered in my tenure as a systems/network administrator, and I have yet to solve it. I have a Windows Server 2003 server that is occasionally "falling off the network". That is, the network monitoring system
reports that it's not responding to pings, it will lose connections to network-attached storage (which kills our backups), and no workstations can connect to it. A minute or two later, it'll be back. During this time, a netdiag run on the server shows no problems.
Sometimes the server will be online and the majority of workstations can connect to it, but not all. I'm sitting at one such workstation right now; it can't ping the server or access shares on the server yet the workstation next to it can. There's no difference
in the workstations; they've both been imaged recently.
I've tried as many standard troubleshooting steps as I could think of and researched some more, but haven't had any luck so far. Research is difficult because it's hard to describe the problem and/or it seems like not many people have encountered such a
problem. Does anyone on the forums know what I'm talking about?
Thanks! :)

Hello,
are using DNS names to ping the server?
Is this server multihomed? If yes, you can try to disable DNS registration on the second NIC of the server and try again.
