The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Exchange 2003 no longer able to send or recieve messages from outside our domain.

Asked by climberboy in Exchange Email Server

Tags: exchange, 2003

I broke Exchange somehow, and I'm pretty sure I KNOW how. I just do not know how to fix it. Any help greatly appreciated.

Here is the VERBOSE version. If you want to save some time, SKIP TO NUMBER 8.

1) Installed AD on two servers. DC1, and DC2.
2) Ran pre-install preparation for Exchange... including upgrading to Server 2003 R2 on both servers, ForestProp, DomainPrep, etc...
3) Created all appropriate DNS entries inclduing @, Cname, and MX Records. Exchange server is priority 0.
4) Routed all appropriate ports through our corporate firewall, created PTR (ReverseDNS) Records to the Exchange Server.
5) Installaed Exchange with default settings. EVERYTHING WAS WORKING FINE TO THIS POINT. Outlook web access is up, internal / external SMTP relaying was working fine, public folders, the whole 9 yards.
7) I noticed that the Default POP3 Virtual Server would not start. Here is where I screwed up.
8) I went through the configure your server wizard on the DC running exchange, and set it up as a mail server, which enabled windows POP3/SMTP services. I figured that Exchange needed that POP3 service in order for the POP3 virtual server to run. It didn't work.
9) I went BACK through the wizard and removed the "Mail Server" role. This was apparently a huge mistake. Exchange immediately stopped sending and recieveing messages from external domains. When attempting to send to our domain (vs-us.com) we immediately get the following bounce message:

Subject: Delivery Status Notification (Failure)
From: postmaster@DC2.vs-us.local To: eric@pixelninjas.com

This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
ericb@vs-us.com

10) Additionally, messages that I attempt to send out through exchange to external domains never arrive. I have not recieved bounces on this issue as of yet.

Again, any help is greatly appreciated.
