Hello,
 
We have nameservers supporting utmck.edu and delegate the zones used by
Windows to Windows nameservers as follows:

When I do a nslookup or dig I only see the first two servers and not
sec2:
--
ns-1: nslookup
 set type=ns
 _tcp.utmck.edu

Non-authoritative answer:
_tcp.utmck.edu  nameserver = pri1.utmck.edu
_tcp.utmck.edu  nameserver = sec1.utmck.edu
 
Authoritative answers can be found from:
pri1.utmck.edu   internet address = 165.6.12.12
sec1.utmck.edu  internet address = 165.6.14.13

Is there anything wrong with this configuration? Why is the sec2 server
not seen
in the query for nameservers?
 
Thanks very much for your assistance.

I am not sure which DNS server you queried.  The server returned a
result from its cache:

and it told you what the authoritative servers are:

You added the server

 sec2.utmck.edu

but that information has not yet gotten to the cache on the DNS server
to which you sent your query.  The rold informaition  will remain in
the cache until its TTL expires.  Then the next query for those data
will result in fresh information being retrieved from one of the
authoritative servers into the cache.

try setting your query focus on the primary.


ns-1: nslookup
 server 165.6.12.12
 set type=ns
 _tcp.utmck.edu


Also, become more familiar with the dig command.  It's much better 
than nslookup.


dig @165.6.12.12 _tcp.utmck.edu. NS
