	The output from "doc" (deleted) definitely shows that this was a 
separate zone, because it had its own NS records, delegated from the 
parents.  However, there were some synchronization problems with the 
parents, as well as the NSes for this zone.

	That's screwed up.  By definition, if you have a zone, it's 
supposed to have a separate entry in /etc/named.conf.

	Not surprising, if they didn't have separate entries in 
/etc/named.conf for the zone in question.

	Previously, under BIND 8, this is probably what happened.  This 
is an error, and BIND 9 corrected this.  Putting separate entries in 
/etc/named.conf for the zone on the secondary servers fixed this 
problem, as they were now able to see the child zone and pull the 
records for it.
