Newbie setup help

[Dimitri Yioulos]

Hello to all.

While I'm a seasoned sysadmin, I must admit that 
I've never worked with BIND ... until now.  I'm 
tasked with setting up DNS on a colocated Linux 
server.  Here's more info., as provided by a 
manager, who thinks I know all about BIND (no, I 
didn't lie to him.  He ASSumed, and I wasn't 
about to tell him I couldn't do it):

DNS, we are using a combination of host files and 
DNS from our AD system currently. Our internal 
domain is "intdomain", our (primary) external 
domains are "external.com" & "externalinfo.com". 
Our internal windows machines need to 
point "externalinfo.com" to our outside 
production IPs at the colo but our linux machines 
need the names to resolve to their inside IPs. So 
I would like to have a DNS server at the COLO 
that the RH machines can get internal addresses 
from for "externalinfo"/"external" outside and 
relay requests for internal to the AD server.

Would someone be kind enough to help me flesh out 
how to set this up or, if there are example setup 
scenarios out there, where I might find them.

I would be most grateful!

Dimitri
