Are the DCs that the zone is disappearing from all in the same domain?
I suggest, especially since you are allowing dynamic updates, that you use
AD integrated zones.
But only convert the primary to AD integrated and delete the Secondary
zones. Point all DCs to one server for DNS then from the server that all DCs
are pointing to, use ADUC, expand System, select MicrosoftDNS, delete the
zone object with the domain name. Then create the new zone in DNS make it AD
integrated, set it to allow dynamic updates, restart the Netlogon Service
and run netdiag /fix from all DCs.
Use DCDIAG to test all DCs and once all replication errors are gone you can
change the other DCs to point to themselves for the Alternate DNS on their
NICs.

You must pretty much use the process to re-install the Active Directory
Integrated zone.

On a side note make sure the child domain is delegated in the parent.
