In fact, there is no real PDC, but I understand what you mean. My two
Windows 2003 boxes are Domain Controllers, DNS runs on a bind-9.3.1 linux

The Netbios names that are set in smbd/nmbd, are already registered with DNS
when the network comes up (Dynamic DNS). This will only work properly if you
have one single Netbios name per machine (Or run several instances on a
multi-homed box).

Windows boxes (NT 5.1 and later) are used to primarily look up 'simple
hostnames' (hostnames without a DNS suffix, whether in a Netbios context or
not), suffixed with the system DNS Domain suffix (list), or connection
specific domain suffix (set by, for example, DHCP). I find that Windows is
'confused' as soon as I also provide a WINS server (but hey, didn't I expect
at least one undocumented feature??).

Kind regards,
