External Web and Email servers

[juicejug]

We have our website and email hosted with an external web host. We
would transfer everything to local but bandwidth is hard to come by at
our location. What do we do to set up our AD with the same domain
name as our web (to allow for future transitions to local) and connect
to our current host?

It's called "shadow DNS" (aka "split DNS") where you
setup your internal DNS zone with the same name but
SEPARATELY with its own Primary.

You must manually add all external records to that internal
version (if you wish your internal clients to contact those
external resources) and HAND manage any changes to the
public version by duplicating those change manually on the
internal.

Most people talk about this as if it is the same "zone" but
really it is TWO ZONES that happen to have the SAME
NAME.

BTW, if you need to ask about this you probably should
pick a DIFFERENT name for your internal Domain &
Zone but we will be happy to help you if you really want
to go this way.

Some people discourage this in general but I have some
Domains setup this way and it isn't really very hard once
you get the idea.

I understand using the second name. I thought I had mentioned in my
original post that the reason for this was that we are adding exchange
and want to fully manage email but still have the host control the
hosting of our web site, therefore we will be using the same name.
Sorry. Is there any MS link with more info on how to setup the split
records you mentioned?

You "therefore" is likely misplace as there is not requirement for this
based on what I understand you to be saying.

Hosts can answer to many names -- live in one AD Domain and
have many DNS names known to others.

No Exchange server should be placed directly on the Internet
unless you are absolutely an expert AND you have no other
viable choice either.

An email server does not even need to be in the same domain
to host email for that domain name; ISPs do this all the time.

Sorry. Is there any MS link with more info on how to setup the split
records you mentioned?

What else do you want to know? There really is nothing to
the setup (there is a wizard in DNS) if you merely understand
the goal:

A Primary with optional Secondaries inside.

A Primary with optional Secondaries outside.

Any record added or changed on the outside must be manually
maintained on the inside by you.

(Inside you might substitute AD-Integrated for the Primary and
optionally for the Seondaries but the principle remains unchanged.)
