I have a problems with Conditional Forwarding in Windows 2003 DNS.

First the Background.
We have a active Directory Domain called something.com which DNS in integrated in AD.
This Domains has 2 DNS servers, which are also ours DC and GC
The We have an Unix Domain Called something.net but also with have an Internet domain called something.net too

The Unix Domain has its own DNS server and here where the problem begins.

The Unix Domain are only use by internal application use by the servers.
The NT Domain its use for End Users.

So my problem is that We had set up a condition that when you try to do a query for the domain something.net should first go to the Internal Domain something.net and if is not found there go to the DNS of our Internet Domain.

But for some reason this isn't working .

I try an NSLOOKUP to ftp.something.net should found it on the Internet domain but I just received this error
------------
C:\>nslookup
Default Server:  DC1.something.com
Address:  172.22.xx.xxx

ftp.something.net
Server:  DC1.something.com
Address:  172.22.xx.xxx

*** dc1.something.com can't find ftp.something.net: Non-existent domain
-------------------------------------------------------

Its like isn't even looking in the right place.

-------------------------------------------------------------------------------
I ran a DCdiag test:dns and all went just fine, no even a single failure
------------------------------------------------------
We have our DNS forwarders are setup as follows.

Forwarders

ALL other DNS Domains
are pointing to 2 of ours Internet DNS

extranet.net
Pointing to out DMZ DNS

something.com.do
Pointing to our Unix DNS which then point to the correct address for our Email Domain

Something.net
is pointing to our Unix Domain DNS & to our Internet DNS

Thank you

If the internal DNS server hosts something.net, it will never forward any requests to the external DNS server hosting something.net.  It will just look in it's own something.net zone and if it can't find the record you're looking for, it will return a 'not found'.  You need to add all the external something.net records to the internal something.net DNS server.
