Computers disappearing from network neighborhood without reason

[me19562]

Most of the computers had disappear from Network Neighborhood and the NT 4 Workstation can't access some servers
Any ideas?

Any chance that those computers have been disconnected from the network or turned off? Rule out the obvious first. Were there any changes in your setup shortly before the problem began?

Check throughout your network to make sure there aren't any rouge Browse Master.. Not necessary the only thing that can cause this but some funny things happen when some Win9x boxes decide the fate of the network browse list.

Another thing is to perhaps check your WINS servers to see if there are some problems there.
