There is no PDC or BDC. That idea died with NT4.0
There is a PDC FSMO "Role" but it is not the same thing.
I assume by the description that the Child Domain has two DCs? If
not,..make one,...out of junk hardware if you have to, or create on in
VirtualPC/VirtualServer on a solid machine.
Make the "good" one the GC.
Run DCPromo on the bad one and make it a member server.
Uninstall DNS on it.
Reinstall DNS on it.
Do not configure DNS on it beyond just installing it,..stay away from the
DNS MMC
Run DCPromo on it to make it a DC again
Transfer whatever FSMO Roles to it you want or just leave it as is.
You can make it a CG if you want, but not required.
If your second DC was a "temp" one made from "junk" hardware or a VM, then
DCPromo it down to a member server,..then standalone, then remove it. The
DCPromo should transfer all FSMO Roles (except CG) to the remaining DC.
General DNS stuff:
The DCs in a Domain (or Child Domain) have the TCP/IP DNS specs point to
themself first and then each other (assuming you're running more than one).
They do not point to any other DNS Server. Active Directory Replication
already makes every DC in the Forest "aware" of all the Zones from the other
DCs in the Forest.
The ISP's DNS goes in the Forwarders List in the DNS Config (in the DNS
MMC). The firewall needs to allow the DC to make outbound DNS queries.
All Clients use only their own DCs in their own Domain (or Child Domain) for
DNS resolution and should not use anything else.
Anyone is welcomed to chime in if I left something out or screwed something
up,...I do that sometimes.
