Scenario:

-An existing network consisiting of 1 Win2k domain controller that runs DNS, DHCP, and Exchange 2000, including OWA.
-Added 2 Win2003 domain controllers running DNS and DHCP, and 1 Win2003 member server running Exchange 2003
-After installing Exch2003, all services and function run as expected, however when I move 2 users' mailboxes to the Exch2003 server, they can no longer access OWA from the outside world.  When they type in the address "www.domain.com/exchange", they get a logon dialog box, as expected.  They type in their username (domain\username) and password, and IE returns "Page cannot be displayed.  Cannot find server or DNS error."
-All users still homed on the existing Win2K server can access OWA as they should
-Users on the new Exchange2003 server CAN access OWA from inside the network.
-It would seem that I need to publicize the address (or port forward) for the new server, but when I dealt with Exchange 5.5, I only needed one OWA server to handle all of my Exchange 5.5 servers.

What's the difference between the OWA versions?

How do I make the accounts on the new server accessible without need another public address?
