I have a test domain setup with a single Exchange 2003 server that is also the DC. I've added a second DC and it also has Exchange 2003. I've moved one of my test mailboxes to this server but it can not receive any mail from any accounts on the original Exchange 2003 server. What must be configured to get these two to work together? The test domain is on the internet. So it can still send and recieve just fine. What settings need to be configured for this second Exchange box to work correctly with the first one?
