If you do not have the _msdcs zone then you would appear to be using
the 'old' dns, which didn't have the _msdcs zone. The W2k and the early
2003 servers used a different dns setup to the one used now. I am not
certain which dns the early Samba DC's used.

This may help, but you use it at your own risk:
