Hi there ! I have Exchange 2000 runing on a Windows 2000 Server (SP4) with AD and DNS enabled. I'm trying to administer this server from my machine runing Windows 2000 Pro. with SP4. My machine resideds in another domain (DomainA) and the server resides in DomainB. DomainA runs on a NT 4.0 Server (PDC). Both domains are in the same LAN (for testing purposes). When I open the Exchange System Managemer console in my machine, I get the following error: The specified domain either does not exist or could not be found. Can anyone provide any hints ? Thanks a lot !
