We have the server duplication problem as well. For example:

Notice that A records are reported back multiple times - in fact,
operations.dccs.upenn.edu
is listed 5 times in the NS request, and reports 5 addresses (all the same)!
Then,
remote.dccs.upenn.edu is listed 6 times in the NS request, and has the same A
record come
back 6 times!
The last server, GRASP.CIS.UPENN.EDU, is not running the Ultrix 4.0 named. It
is using bind 4.8
on a Sun. It reports the correct information, but got its zone information from
then primary
name server operations.dccs.upenn.edu. So I don't think it is a problem of
configuration - just
a bug with the Ultrix 4.0 name server.
