Exchange 2003 OWA only authenticates IP Address Users

When users outside the WAN type in dns adress and attempt to log in to the OWA server, the server does nothing and displays the login page again.  If a user uses the public IP address, they can then log in.

Users within the WAN can specify the server name and login, they don't need to use an IP address.

Any ideas?
Thanks!

***UPDATE***
The OWA accessed by the DNS name works in both Chrome and Safari.  It seems not to work in Internet Explorer.

At first glance it sounds like a public DNS lookup failure.  I would be using NSLOOKUP to confirm what the OWA's public FQDN resolves and verify if it is the public IP.

However, in our update, you indicate that it works for Chrome and Safari users, but not IE users?  Is this still limited to just public internet connected users?

Our local DNS server had a bad forwarder.  I removed it, and all is fine.
Thanks! :)
