I'm looking for a way to provide DNS for some internal addresses for a
domain without the DNS server being authoratitve for the entire domain.
Here's a scenario....

Internal Win 2003 DNS server servicing domain.com & others

I need it to resolve internal NATed addresses for a few hosts.

hosta.domain.com = 10.10.10.x
hostb.domain.com = 10.10.10.x
hosta.domain2.com=10.10.11.x
hostb.domain2.com=10.10.11.x


Anything not specified on the internal Windows DNS server should forward the
request to the Domain's/ISP's authoritative DNS server to resolve the public
address that the host sits on.

anythingelse.domain.com = rely on outside (authoritative) nameserver
anythingelse.domain2.com = rely on outside (authoritative) nameserver
