<br>
I have a subdomain delegated from AD to a bind9 instance I have running that<br>
so that all requests for that subdomain are sent to the bind 9 instance. I<br>
would then like to set up zone forwarding so that further subdomains can be<br>
managed by other bind 9 instances.<br>
<br>
I know the forwarding is working because I can query the main bind9 instance<br>
at receive the expected results. However if I query from the AD server that<br>
is doing the delegation I get a SERVFAIL error.<br>
<br>
Am I trying to do something that is not possible or am I just missing some<br>
configuration.<br>
