I am attempting to connect users that log into a domain controlled by a 2000 server to a 5.5 Exchange server hosted on NT. There is a one way trust between the 2K domain and the NT domain. (NT domain trusts 2K domain) You can create a mailbox in Exchange and make the user of the 2K domain the owner. However, when you try to connect to it from the 2K domain, you are prompted for a username and password. Nothing I enter creates the connection. What am I missing?
