Lets see if I understand correctly what you have done:

You had a Samba NT4-style domain and you have classic upgraded this to a Samba AD domain

You were running Bind9 on the NT4-style PDC and you want to continue running it.

You were also running a DHCP server on the NT4-style PDC and you want to continue running it.

Is all this correct, if not please describe your setup better.
