computer disapearing from browser

[Tony]

Hi
We have a recurring problem where some servers will temporarily
disapear from the browser list. It is still possible to put the UNC
path in & get to the server but it is not possible to browse to it. It
is usually the same servers each time and can be several weeks between
each disapearence. They reappear after a while, which could be a an
hour or so, to 12 (ish) hours.
Network is all Windows & servers are mainly Win 2003, boxes doing the
browsing are all Win Xp. All have latest patches on.
Any help & thoughts appreciated.
Thanks
Tony

A lot depends on your network. Is it one subnet or multiple
interconnected subnets with a WINS server? If it's a single subnet,
then the problem is most likely due to a firewall problem on one or
more computers. The best way to troubleshoot these issues is with
browstat.exe (supplied in resource kits). Read this article:

"Troubleshooting the Microsoft Computer Browser Service"

Note that just one computer on a subnet with a misconfigured firewall
can kill all browsing on this subnet:

Thanks John,
We have a multiple subnet network spread over 30+ sites.
I think it is a browser election issue. Users can see other servers in
the same subnet as the ones thay can't see. When the servers
disappear, it is the same servers across the whole network.
Might disable WINS on one segment for a while to see if the problem
returns.
Thanks again
Tony
