http://www.ISAserver.org Dear Dr. Thomas W Shinder! I got this problem. My server is using ISA server, from this server I can use Microsoft Outlook 2002 to connect to Exchange 2000 Server (using Microsoft Exchange Server option, it means I use the Exchange Client to get Exchange Server). But with my workstation in LAN, I want to use Exchange Client in LAN through ISA Server using NAT, but everytime the workstation wants to get Exchange Server, it said that my username or domain name is not invalid. I don't understand. I am using DSL connection to connect to Exchange Server. Thank you so much.
