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.
