Anyway to use a forwarder when record not found in my authoritative zone?

[Chris Cox]

I have a BIND 9.3.x server.

It is autoritative for a zone called csg.stercomm.com

Before.. Windows was authoritative over the zone.

Under Windows, when I query certain unqualified addresses,
the Windows DNS will return a result as if it found
the answer in csg.stercomm.com even though the record
IS NOT inside Window's DNS csg zone records (not sure where it
comes from).

Let's say I query the name "web" using the Microsoft
DNS.  nslookup (etc) will find it as web.csg.stercomm.com
with some IP address.  BUT when you look at the DNS
server itself, there is NO entry for "web".

My guess is this could be some kind of global
forwarder.  My problem is that the box appears to
be authoritative for the zone... so how is this done?
Maybe it's some sort of WINS smashing into the zone
that Microsoft supports?  All I know is that the
server says the entry was found in csg when queried,
even though the record simply isn't there when looking
at the administration panel.

Specifically, I'm looking for a BIND soln to this.
I wondering how do you configure the server to look
inside of its csg.stercomm.com zone data (for which
it is authoritative for) and then if no record is
found, attempt the request via a forwarder.

I know I can do this with search lists on the client
side... but does this mean that the Windows DNS
can do things that ISC BIND simply cannot do?  Anyone
have a soln (the search list thing has numerous
drawbacks)?

Thanks,
Chris
