For me it is: the problem is that if I shut down the PDC, BDC won't be
able to update it's DNS zones because them need to be a full replica and
not a partial one.

are fully replicated while for me not.

Please tell me if for you them are fully replicated and if shutting down
PDC, BDC is still able to work (allow logins, dns updates and so on).
