Thanks for the quick reply John,
I answered some of the items in-line
>First things first, some more info on your overall DNS infrastructure
>and how the 9.3.2 server fits in would be helpful.
>- Is this for education.ucsb.edu, other zones, or both?
The NS is ONLY for education.ucsb.edu
>- Is the 9.3.2 server authoritative-only, or does it serve recursive
>requests as well?
It is autoritative for education.ucsb.edu only
>- Is the 9.3.2 server listed in any of the NS records of the zones you
>host, or just the SOA record (public vs. hidden master?)
Yes, there is an A record for it as well as the SOA records and it is public.
>- How many slaves are you running? Do all of your zones slave from
>the 9.3.2 master, or do some point to other masters?
I am NOT running any slaves at this point, just this one Master.
