I have two domains that are not in the same forest at all (created before me). Anyway, one domain is a Windows 2003 domain and has the Exchange 2003 server - domain abc.com. Other domain was a Windows 2000 domain and was domain xyz.com ALL users had email services at domain abc.com. Users at xyz.com would connect through a vpn using a RAS server and connect to the exchange server. All client were XP until recently I am trying to implement Windows 7. We finally got rid of an outdated piece of software that kept me at Windows 2000 server and I upgraded them to Windows 2003 server so at least both domain are on Windows 2003 now but Windows 7 does not like the vpn and I cannot seem to get that client to connect to the exchange server. I have created a two-way trust, it is a Realm trust that is not transitive. What am I missing? This should not be this hard although I am new to Windows 7 of course. Thanks for any help.
