Hello, I have a couple of vista laptops with outlook 2007 that need to connect to a exchange 2003 mailboxes. The trouble is the laptops are non domain members, and need to connect in the field as well as on the LAN. Of course POP is not an option as the dns name of the server will not resolve inside the LAN. The DHCP server is a verizon FIOS router and has limited programable functionality. If I were to say use a host file I would run into the same problem.
