In news:AE65F516-238E-463A-B4BD-C01BA6B102C0@microsoft.com,
kjs <kjs@discussions.microsoft.com> made this post, which I then commented
about below:

server is for an entry? I lookup an entry and it always says
non-authoritative server. is this my isp dns? I'm confused. thanks in
advance.

If the name you are querying is under a zone on the DNS server that nslookup
is using, then it will be an authorative answer. If the server does not have
the zone, and it goes elsewhere to find it (recursion process), then it is a
non-authorative answer.
You can use
set q=soa
to find the SOAs for the zone. Once you know the IP, then you can tell
nslookup to specifically use that server:
server 1.1.1.1

nslookup
set type=ns
and this gives the master name server in case the master does not have an NS
record (hidden master)
set type=soa
This returns NS records, SOA record, MX and TXT records
set type=any
There is nothing wrong with a non-authoritative answer, it simply means the
DNS server doesn't have the zone and it got the answer from its cache,
forwarder, or by recursion..
