I setup my servers as slaves of the parent domain, and that seems to
have fixed the problem so far.
It seems like a hack though.
Reading through other solutions to other problems posted to this list
since I joined, I had the idea that maybe I should setup the parent
domain servers as forwarders? but do I really want to push all internet
lookups through those servers and add that additional hop?
Is there some better way to solve this problem?
