migrate to more complex domain design

[Bob Muzzy]

A friend's very small business has a flat domain, e.g.; smallbiz.com. They
want to migrate to something like local.smallbiz.com for internal use and
retain their public IP and FQDN of mail.smallbiz.com. Can this be done? My
guess is they'd have to demote the 1 and only DC, delete the domain
smallbiz, then re promote the server to DC and this time name it
local.smallbiz.com. One potential complication is they've got exchange 2008
running on smallbiz.com. Will the above process work? Will it break
exchange?

Thanks,
Bob

The e-mail domain need not be the same as the active directory domain. As
long as DNS points things to the right place, Exchange should work just
fine.

You didn't ask, but personally, I think that having different domains for
internal and external access unnecessarily complicates things, especially
for some applications. I much prefer a split-brain DNS and using the same
domain everywhere.

Effectively they have split brain DNS now, given that their registrar,
godaddy, hosts their nameservers, & public DNS I.e.; mail.smallbiz.com

I didn't mention it but part of the problem with their current configuration
is their iphones can't access their exchange server when on wifi. I made an
A record in internal DNS for mail.smallbiz.com that points to their existing
public IP for mail, but that didn't fix the iphones. I read another post
saying I should point the A record to the Internal IP instead. I think
there'd be issues with the SSL cert. on mail.smallbiz.com in that case, but
I'll give it a try later.

If they already have split-brain DNS then they could add the external zone
as an internal zone and publish the resources with their appropriate
internal addresses so the URL is the same inside and outside. That way,
WiFi devices wouldn't be traversing the firewalls, proxy servers, etc. when
getting their mail from inside.
