[Samba] PDC with 2 NICs problem

[Roy McMorran]

Hello Samba List,

I'm running a Samba 3.0.22 PDC on Solaris 9.  Things got a bit peculiar 
when I added a 2nd network interface.

The two subnets are a primary network that carries all the client 
traffic and a tape-backup/admin network that is not accessible to any 
clients, ie.
aaa.bbb.ccc.241 - bge0 - primary network (address suppressed)
192.168.254.254 - bge1 - admin/backup network

I've configured Samba (I think) to ignore the admin network...

        socket address = aaa.bbb.ccc.241
        interfaces = bge0 lo0
        bind interfaces only = true
        hosts allow = aaa.bbb.ccc. , 127.

However, some devices are getting the notion that there is a PDC at 
192.168.254.254 and are trying to contact it (which of course they 
cannot).  For instance (this is a NetApp that is a domain member):

grunthos> cifs testdc
...
Testing all Primary Domain Controllers

I'd expect it to find only aaa.bbb.ccc.241 - Any idea what am I missing 
here?

The PDC is also the WINS server, in case that matters.

Thanks,
