Can't browse to server

[jwkh]

We have a workgroup with 2 servers and 5 users. The 5
users and 1 server can see each other in the browser. The
1 server cannot see any of the other systems. We can ping
both ways. We can search for the 1 server ONLY if we add
it in the hosts file of the system. If we add the 1
server into the hosts file, we can search for it and map
drives.

All systems could see each other until we did two things:

1) MS critical updates to the 1 server; AND

2) We closed ports 137, 138 and 139 on our FIREWALL (only
on the firewall). The firewall does DHCP for the 5 users
(servers on static IP).

The systems are all on the same subnet and using the same
subnet mask.

Any ideas?

TIA

2) We closed ports 137, 138 and 139 on our FIREWALL (only
on the firewall).

Undo this. Those are not made available to the outside to begin with, you
should have to block them explicitly.
Then see what happens.

Meant "....should *not* have to block..."
