This may be very unique. But...I have and exchange 2003 server in a domain exchange.ualr.com. I have a client who can login to this domain and everything is fine.
When the client travels to another city the login server is in another domain, city.ualr.com.
But when logging in the domain is changed to exchange.ualr.com in the "Log on to" box
and all network funtions, internet through Internet Explore, drive/printer mapping via a script from the Active Directory in exchange.ualr.com also completes successfulluy and all permissions to drives, folders and servers are intact. However, Outlook will not get beyond
"Your exchange server is unavailable" . Any ideas on how to get Outlook to connect?
