I am using Exchange 2003 in Windows 2003 Server standard with a Cisco PIX firewall.
I am migrating Exchange 2003 servers. I believe I have cloned the setup from the old server to the new one. I have moved all the mailboxes, and I have the internal Outlook clients and external Pop3/SMTP clients sending and receiving email.
However I cannot get OWA to work. If I go the https://Server.domain.com from an external computer, I get the IIS under construction message, which make me believe that the port forwarding is correct. But if I go to https://Server.domain.com/exchange/mailboxname I get "Internet explorer cannot display the webpage". Sometimes when I first type the complete URL is asks me to authenicate before giving me the "Internet explorer cannot display the webpage" error message.
If I use OWA on an internal client with either the internal IP address or internal FQDN, OWA works, but with a certificate error because the servernames do not match, but it has all functionality and can send and receive email.
This makes me think that the clients from outside the building and not being authenicated correctly.
RPC over HTTP seems to be working, which makes me think all the port forwarding is correct and it is an authenication problem.
Any ideas on what I should check. The client is wanting his email working.
