dns queries

[Guest]

Running Windows 2003 network with integrated dns. clients and servers seem to
access both internal and external sites with no problems. I have forwarders
setup and these are correct. When I run a test query from the monitoring tab
within properties of the dns server it fails. When I run a recursive test it
fails as well. When I run an nslookup on my local server it indicates that it
cannot find a server name for the correct ip address. Not sure what's wrong
or how to troubleshoot. I welcome any advice. thanks!

Add a reverse lookup zone that includes the ip address of your server, you
can test this by running the following from a command prompt


nslookup
set q=ptr
(ipaddress of server) and you should get a responce with
x.x.x.x.in-addr.arpa name = server.my.test.domain

Jay, when I create the reverse lookup zone this is the reply I get via an
nslookup

"***dns server(Correct external)dns server name....can't find...then has the
correct reverse ip address.in-addr.arpa: Non existent Domain? It's like DNS
is not installed but it is......any other ideas?

Reminder about AD and DNS: Only use the internal DNS servers (no ISP
servers) in IP properties. If you use any others, no telling what you'll get
in a response, and surely may not get your own DNS to respond, besides
guaranteeing AD to not function properly.

That said, once the reverse zone is created, run an ipcofig /registerdns and
check the reverse zone to see if a PTR was created for the machine's IP
address. If it doesn't, insure the zone was created properly reflecting your
internal subnet.
