Missing DNS GUID CNAME in _msdcs

I've a Forrest root we'll call ROOT and a child domain we'll call CHILD. I recently added a new 2008DC to the CHILD domain. It's not showing with a GUID CNAME record in the _msdcs.ROOT zone when I look at DNS from my CHILD domain DNS servers. I do see that record when I view DNS from my forest root DC. I also notice a CNAME record for a recently removed CHILD domain DC when viewing DNS from the CHILD domain DNS servers, but not on the ROOT DNS server.

I do see an event on my ROOT DC under the DNS Server event log; Event ID 4515 Source 4515, indicating I may have had another zone copy that conflicted.

So it would appear I have a problem in DNS replicating from the forest ROOT to my CHILD domain DNS servers. I'm not sure where to go from here in trouble shooting this.

It should tell you where it's trying to load the conflicting copy from?

Make sure any zone you want to replicate to the child is set to have a scope of All DNS servers in the Forest.  You'll find this on the properties of the zone.
