bmdgi - thanks, if we can avoid renaming the domain that would be best.<br />
<br />
mboppe - thanks, great solution and works for UPN so we can now use username@domainname.com, though doesn't work for the W2K &nbsp;'LOCAL\username' login though

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. &nbsp;However, when we log in we have to use LOCAL\username or &nbsp;user.name@local.ourdomain.<wbr />com<br />
<br />
This is really frustrating.<br />
<br />
Is there anyway to alter our AD setup so that we can log in as user.name@ourdomain.com or just ourdomain\username?<br />
<br />
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<br />
<br />
Any tips to this? &nbsp;I've had a tough time finding the correct google and expert-exchange search strings to find a solution.<br />
<br />
Thanks.

How to use our domain name to log in

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
