If it's giving you the "unknown" then it seems to me you
are not able to reverse resolution either. Since it's able
to reach a DNS server (since there is some response, not a
time out) I would guess that your zone files/AD stuff is
broken some how. You may want to turn on detailed logging
so you can get more information. Check your event logs. Do
you have other DNS servers in this environment or is it
your only box?
