I've got a Samba 3.0.4 server running on RedHat 8.0 as a PDC. It's the
only domain controller on the network, and the only WINS server on the
The problem is, when I browse the network neighborhood, I see the
NetBIOS name of the server ("SERVER") appear as a workgroup/domain
(though there are no hosts listed in this phantom domain). It also
appears as a computer under the AEC domain. All computers on the
network are either in the workgroup AEC or domain members of AEC.
When I attempt to use User Manager for Domains (usrmgr.exe, from
SRVTOOLS) from a Win2K or XP client, I am first presented with the
error message, "Could not find domain controller for this domain. Would
you like to select another domain to administer?" I suspect it is first
trying to connect to a DC on the phantom domain, SERVER. In the "Select
Domain" dialog box, both AEC and SERVER appear as domains.
I have been having some problems that come and go that seem to be
related to browsing, domain group SIDs, and so forth. I suspect that
whatever is causing the netbios hostname appear as a domain may be the
I suspect it's a domain browsing / nmbd / WINS issue, but I'm stumped
as to where the problem lies. I've tried clearing the NetBIOS cache
(using nbtstat -R) then restarting the workstation to no effect. The
wins.dat database looks normal to me.
