I do not know how your dns is setup, but a Samba AD DC must be 
authoritative for the AD dns domain. This usually means that, if your 
registered dns domain is 'example.com', you would use something like 
'ad.example.com' for the active directory dns domain. All domain clients 
would use the DC(s) as their nameserver(s), the DC would return 
information about the AD domain from its own records and for anything 
outside 'ad.example.com', it would ask its forwarder.
