Heres the problem. I upgraded from exchange 5.5 to Exchange 2003 (not the easiest of move, but it went thanks to exmerge). Since it was an upgrade it didn't allow me the choice of naming the organization and we got stuck with an unusable dns structure (abc.bobsworld.com). I'm curious how I can reconfigure it to drop the first portion of the domain so it would be a valid dns structure and our mail won't get returned as undeliverable to many organizations. We have the dns registered and hosted externally (along with our pop3 account) but even after changing our smtp to choose the pop3 as our primary within exchange it still comes back. Can I add another organization dropping the first 3 and will this effect my ad connections?
Any ideas would be appreciated.
