Reverse NSLOOKUP issue involving domain name
Jeff
the vendor says we have a DNS issue to fix for it to work right..The person
who setup our network is not there and I am kind of learning as I go..If I do
a forward NSLOOKUP it resolves correctly..If I do a reverse NSLOOKUP it shows
everything correct EXCEPT the first letter of our domain is capitalized (
Athena as opposed to athena)...I will paste the nslookup -d2 results below
with nothing edited...Can anyone point me in the direction to fix this
please? While I would like to fix it domain wide, I mainly need to fix it
for a server and a few clients so if a permanent fix is something like "
renaming the domain" but there is a work around for a few records I would
appreciate both but probably opt for the quicker/easier one at this
time...Thanks for any responses to help me out and sorry if this is easy but
I just don't know the answer and would like to fix it before the vendor
leaves tomorrow night..

I believe you will find this is picked up from the primary DNS suffix, which
is used in the DNS suffix search list.
You can modify the primary DNS suffix so it does not have the uppercase A or
use a custom DNS suffix search list.
ipconfig /all will show your primary DNS suffix and DNS suffix search list.

Thanks for the response and yes it is Primary DNS suffix... I have been
searching the internet for a little while trying to figure out where to
modify it at and not having much luck...I have browsed the DNS admin tool and
still haven't located where I can modify it...Can you point me in the right
direction by chance if you know where it is? I would appreciate it...I am
looking into the custom dns suffix search list but if I could modfiy the
primary ( without it being a big deal ) that would be better...

Changing the Primary DNS suffix on a DC is best done with a script you can
