[Samba] Bizarre problems with two Samba in the same workgroup

Thu Mar 9 00:32:44 GMT 2006

I had to setup a new Samba server as a PDC in my job (Samba 3.0) to replace
and existing Samba server PDC (Samba 2.2), the old server was running ldap
as backend, the new is running tdbsam. I have a lot of bizarre problems when
I put both in the same workgroup with other machines. I will give you a list
of them:

1) The new server is configured as local master browser and domain master
browser, with this configuration the old server never appears in the network
neighborhood.

2) The servers have the same shares. If I define a new share in one of them.
the share appears in the other if I see it in network neighborhood. The
content of the shares of the new server are the same of the old one if a see
them in the network neighborhood (although they are not the same).

3) There is a share defined in the new server (documentacion) that doesn't
appear in network neighborhood (I can only connect to it from command line
with smbclient) eventhough the same share works ok in the old server.

4) If I do nmblookup -MT <Workgroup> the result are the IPs of both servers.

5) The home of my user doesn't appear in network neighborhood but other
users appear ok.

Next I will give you the content of smb.conf of both servers:

I would be very grateful if anyone can tell me what's wrong or point me to a
webpage, file, post in a samba list, or any source of information.

Thanks in advance
