Can't Access Exchange Administrator in New Installation

AtomicToad used Ask the Experts™
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.

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.
Okay, first of all, let's use the Exchange System Manager to manage Exchange 2000.

Start\Programs\Microsoft Exchange\Exchange System manager. The error code you are giving is a 5.5 code.

The user accounts are managed in Active Directory. When you delete a mailbox, or create a mailbox, you do it in ADU & C.

When you create an account in Active Directory, in the wizard when it prompts you to create a new mailbox, say yes. Then wait a couple of minutes and go to the properties of the user account, check the Email addresses tab, are they getting stamped by the Recipient Update Service?

In Exchange 2000, the Exchange administrator does not have rights to logon to all mailboxes any more. In 5.5 the Exchange service account (by default) could login to any mailbox, in Exchange 2000 you must give the Exchange administrator send as and receive as rights on the mailbox store. (which you can view in the Exchange system manager)

Also in Exchange 2000, relaying is prohibited by default, my gut feeling is that something was changed on the settings which is now prohibiting anyone from sending. No matter what state the Exchange services are in, you will be able to at least get into the Exchange system manager to view settings. You also do not have a connector like we did in 5.5 (The IMS), the default virtual server does everything right out of the box using the SMTP service. Go back to the SMTP default virtual server and make sure the relaying is not set to tight.

Make sure you are using an account that has Exchange full adminstrator rights. (Or the account you used to install Exchange)


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!
