How to use our domain name to log in

A team of ours recently exposed some of our software to the Internet, and for a while we've had OWA access to Exchange via the public interface.  However, when we log in we have to use LOCAL\username or  user.name@local.ourdomain.com

This is really frustrating.

Is there anyway to alter our AD setup so that we can log in as user.name@ourdomain.com or just ourdomain\username?

Ourdomain.com is hosted at our ISP DSN provider (but that should really just be for our web stuff, I would think), and in Exchange and Active Directory our emails are all setup as username@ourdomain.com

Any tips to this?  I've had a tough time finding the correct google and expert-exchange search strings to find a solution.

Thanks.

You can try a domain rename tools from microsoft to change your FQDN for ourdomain.com..

But if you change your active directory authentification for user.name@ourdomain.com, All you Internal DNS will need an update. Because a local user, when he will try to go under www.yourdomain.com, this will resolve locally.. you will need to add A record for every of your services...

I hope this will help you.

bmdgi - thanks, if we can avoid renaming the domain that would be best.

mboppe - thanks, great solution and works for UPN so we can now use username@domainname.com, though doesn't work for the W2K  'LOCAL\username' login though
