NetBios computer names and SP2

Hi,
I have a small network with 4 computers (2 win2K, 1 win2003 and a laptop
running XP SP2)
one of the 2K is my gateway to internet and acts a s a dhcp for the rest
(using the network 192.168.......)=
Before SP2, I ll machines connect to each other using computer names. Since
SP2 and it's firewall, when firewall is active, I can not connect to other
machines from my laptops to other machines nor the other machines see my
laptop. I need to use IP addresses.
When I desactivate the firewall, everything goes Ok and I can connect using
netbios names
I checked the firewall config, in exception tab there is the file and
printer sharing enabled with all necessary ports (default config which I
never played with)
Should I do or add something else in order to be able to use netbios names?

Thanks in advance

First of all, as long as a firewall is active on the direct
Internet connection, i.e. on the outgoing connection of the
Internet gateway computer, and as long as no unsafe computers
connect to your LAN, you can leave the firewall off for now. At
least this gives you more time to solve the problem.

If you want to find the cause of the problem, you may have to
analyze the computer browser system of services running on your
computers. As far as I can tell, your firewall is set up
correctly. As long as the exception for File and Printer Sharing
is enabled, it should work. If it doesn't, you can try to use

You're in the wrong newsgroup and should post a new question in
