I'm trying to diagnose a problem with mailbox access via OWA on a network. The client has a DC running Windows 2000 and Exchange 2003 SP2 and a Windows 2003 terminal server. The strange thing is there are 2 routers on the network - the gateway for the Terminal server is an SDSL router (192.168.1.200) and the gateway for Exchange server is an ADSL router (192.168.1.1). OWA can be accessed from within the network but not from without. Not at DNS problem as TS works fine using the FQDN and port 80 is open on both routers. SSL not being used yet.
Any suggestions why this should be so? Cheers.
