Forward zone problem

[Stefanick, Andrew]

I am struggling with a forward zone issue in Bind 9
 

We have many forward zones configured and they work fine.  They really
amount to no more than a forward directive such as

 

 

zone "name.of.domain" {

    type forward;

    forwarders {w.x.y.z;};

};

 

 

We put in a new one, and it will not work.  nslookup shows it seemingly
only trying to resolve the query internally.

 

If I set the server to the IP of the forwarder in the nslookup, then we
can resolve the queries when posed directly to the remote DNS server.
So, it is not a networking issue.

 

I do not understand the logic/sequence that occurs when a query is posed
that should be sent to a forwarder.  Where do the root-server  records
come in, and why even.  Doesn't the forward directive tell the server,
"don't even bother, just go to w.x.y.z for the answer"

 

here are some example of using dig against some of the forward zones
that work.  The AUTHORITY section shows the name of the remote DNS that
controls the domain.

 

When I try dig for the new forwarder, the only AUTHORITY that shows is
the A.rootserver.

 

I really don't get it.

 

I ONLY put in the 3 line directive, and I am done.

 

I don't even know what to change/try.  It is too simple to implement.
