OWA 2003 not working after upgrade this weekend

I upgraded my Exchange server to 2003 enterprise this weekend and almost everything is working great.

I was running Exchange 2000 on a 2000 SBS server.  The new Exchange server 2003 Ent. is running on a 2003 server that is also a DC in the domain.  The 2000 server and Exchange 2000 are still active in the domain.

If I try OWA inside my network to a mailbox on the new server I have to authenticate 2 times but it works.  Outside the network after the username and password is entered I get a message that there may be a DNS error and the new server can't be found.

Internally and externally if the mailbox exists on the old 2000 server everythign still works fine.

I want to get this working without FBA, SSL or installing a Frontend server.  Is this possible and what is wrong?

Where does the http traffic point to?
If it is pointing to the old server then that is your problem. Without a frontend server you can only point to one or the other.

Any reason why you aren't using SSL? I wouldn't deploy OWA without out.

Thanks for the reply.

I will likely implement SSL and forms in the future.  I just wanted to do the upgrade and get the environment stable with all of the previous functions.  The only reason this isn't a major problem is the 5 heaviest email users in the office have blackeberries that I run off of our BES.

When you ask where the http traffic points to are you talking about somewhere in the Exchange server config or from a router, firewall perspective?

Router/Firewall. Exchange doesn't care.

Thanks.  I looked at my firewall again and saw that the http traffic was being routed to the old (Exch 2000) servers IP address.  I just pointed it to the IP of the Exch 2K3 server and I'm working fine.  Thanks again.

Stay tuned.  I'm not sure that my public folders are replicating.  I read all over that it takes a long time.  But if I can't find a way to determine in it's at least moving slow or at all I'll post another question.
