Here is the situation, I installed Exchange several times in the last month trying to get a proper build. I finally think I have a good build. I have two DC's running AD already (populated with about 30 users). On the network I have several servers, but most importantly an Exchange 5.5 Server named "QUASAR". The server I installed Exchange 2000 on is "BALTEXCH01". First of all, when I followed the instructions by MS, and by "QUE"'s book to migrate users, there is no "Move Mailbox" option, how in the world do I copy all the Mailbox store off of 5.5 onto 2000?!? Secondly, I can login to the server using IMAP fine, but when I attempt to login to HTTP, I get the login prompt three times, I enter a password I know is good, and then I still continue to receive "HTTP/1.1 401 Unauthorized" errors. Is there some configuration I am missing? The previous build I installed, and then I could not login to the server, but I could reach the public folders. Then I let it sit about a week without touching it, and out of nowhere, I could login fine (I'm assuming I forgot to replicate), are my problems maybe something very similar?
