Can't Browse Samba Domain Computer Lists from Windows XP Clients

[gkoo]

Hi everyone. I've setup samba as a domain controller. Everything works ok, i can join the clients in the domain. My PDC also acts as a WINS Server.

From the client computers i can ping other clients by using the NETBIOS NAME.
From the clients i can also acces other clients or the pdc using the \\netbiosname in windows explorer.

My problem is that i can't browse my domain and see all the computers in it. I get the following error :

DOMAINNAME is not accessible. You might not have permission to use this network resource. -> The network path was not found.

If i do a smbtree on my PDC it shows all my computers in the domain with their shares.

Any suggestion is welcome. Thanks
