I have two Exchange 5.5 boxes on NT4.0 computers. Both have the same service packs (3), and (6a) on the Server. When I move a mailbox from Exchange1 a (BDC) to Exchange2 (a standalone in the same domain), you are asked for your name and password each time. The password is not being authenticated from your logon. Do I need to make Exchange2 a (BDC) also.
