Resolving DNS sub-domains


C

ctvader

I have a question/confusion about resolving DNS subdomains. Say I
have a domain called name.com. I created a sub-domain called
sub1.name.com, added that domain to the append dns suffixes on the w/s
and can resolve hosts in sub1.name.com by just typing nslookup host1.
here's where I'm getting confused - I created another sub domain
called sub2.name.com, added the domain to the append dns siffixes on
the w/s but I cant resolve by just typing in host2 - I need to type in
host2.sub2 to resolve the name. What am I missing? I know its
something silly...

Did you create sub1 and sub2 as sub1.name.com and sub2.name.com on a
different DNS server in teh child domain or did you simply create sub1 and
sub2 under the name.com zone?

Is sub1 machien on the same subnet as name.com?

If so, is sub2 machine on the same subnet as sub1 and name.com?

Do you have both sub2.name.com and sub1.name.com on both machines?

It could also be simply a misspelling in the search suffix as well.

I found the issue - this has to do with a setting in our GPO, setting
what domains we resolve in the suffix search order. Thanks for the
suggestions.
