Hello,I am figuring out how to publish my Exchange server 2003 to internet?I am familier with the process but would like to know exact step.My internal domain is abc.comregistered domain for mail is efg.comInternal mails are working.Now want to publish exchange on internet.I have 1 public IP given by ISPI know I need to register MX records.And also I read I need to establish internet connector.Any1 can explain step by step process?Thanx,Amey.

Since you mentioned about internet connector, I assume that you are using SBS 2003, please correct me if I have misunderstood it If you are using SBS 2003, please the articles below to configure the SBS server: How to configure Internet access in Windows Small Business Server 2003 Configure Your Server to Connect to the Internet Configuring Incoming and Outgoing Email for Windows Small Business Server 2003 Yes, MX record has to be set up, the article below will help: How to setup your MX record

I am using Windows Server 2003 R2 Standard edition. It's not SBS server.I am going through the links you added.

I see. Its a pure exchange 2003 environment If you have a small or middle size exchange organization, we can use IMW (Internet Mail Wizard) to configure the internet mail access, please follow the Internet Mail Wizard section in Transport and Message Flow Features of Exchange Server 2003 If you have a large or complex exchange organization, please follow the Manually Configuring Your Exchange Server for Internet Mail Delivery section in Exchange Server 2003 Transport and Routing Guide

It's a single Exchange 2003 server.Yes I figured that out. I need to use "Internet Mail Wizard" & will need to specify probabbly public DNS of ISP's. Do you have any link with snapshots of Internet Mail Wizard steps? I am actually going reverse to solve DNS problem. In event logs some times my exchange throws DNS error of of ISP's. My doubt is that the specified DNS while configuring Internet Mail Wizard are different than which we updated another DNS IP's of same ISP some months back. As building Exchange is not my everyday task I cant remember those steps. Regards, Amey.

Heres the link with the snapshot

Any update? Does the articles help?
