Ports 137 - 139 should work, but there may be more, search for the list of
well known ports, there are several out there.

Do you have firewalls in between your subnets?

Well the topic says most of it I suppose.
I'll explain the situation.
I have a domain spanning several class C subnets with firewalls in between
them, all on the same LAN though. Now Im wondering which ports will need to
be opened between these nets for browsing to function properly? The PDC
along with a BDC are both on the same net, and the computers on this net are
visible when browsing the domain, no computers from the other nets are
though.

Servers are NT4 Sp6a, and clients are mixed NT 4 and 2K.
The network is a switched 100 Mbit LAN, using Cisco Catalyst 2900's if that
matters.

Regards
Johan
