Can't Access Exchange Administrator in New Installation

Hi Everyone.  I am an Exchange newbie.  I'm trying to install Exchange, and everything seemed like it went well, but there are some problems -- I was able to send one mail message, but now every time I try and send a message I get an error that relaying is not allowed, and I can't access my mailbox on the Exchange machine when I use a user account and the correct password.

The Exchange machine is also the Domain Controller, and I can logon to the domain fine.  The user accounts work, but I still can't access any exchange mailboxes.  I can telnet to the exchange machine on port 25, but can't send mail because of relay security.  

I can't even play with the settings because when I try to open Exchange Administrator I'm prompted to enter the name of an Exchange Server, and when I enter the name of the server (which is also the machine I am on), I get an error "The Microsoft Exchange Server Computer does not respond," ID number DS_E_COMMUNICATIONS_PROBLEM.

Does anyone have any idea what I did/am doing wrong?  I ran forestprep and domainprep, I followed the guidelines, all the services are running, but I can't connect to the server through Exchange Administrator, and I can't login to the server even when I'm already logged into the domain on the same account, and the domain controller and the exchange server are the same machine!  I must have done something horribly, horribly wrong.

Thanks!

What version of Exchange? What type of domain - NT 4 or AD?

Ahh -- sorry about that.  The Server is running Small Business Server 2000, so Exchange is 2000 and the domain is Active Directory.

kevala, thanks!!  This was exactly what I needed.  Apparently my problem was that I created the users BEFORE installing Exchange 2000, which was a bad move.  When you do that, you don't get an email tab, and even though the users are in Active Directory, they still don't have mailboxes.  Administrator gets upgraded automatically to have a mailbox (postmaster), but the other accounts are mailbox-less.  Following your short but excellent tutorial, I just added new users and specified that they should have mailboxes.  Our MX record hasn't been switched over yet, but internal mail works fine, so I'm branding this server as "up."  Excellent job -- thanks again!
