Re: DNS Timeout error..Please advise

The zone is named "umc.ufl.edu" and we do not have any wildcard records.

If I go to a box that belongs in a differnt zone and do a nslookup using the
fqn, you can see where nslookup appends the name 2x, but never times out, as
does "umc.ufl.edu". This zone is on the same box where umc.ufl.edu times out.
These are my results:
