It turns out you were right. Would you believe that Service pack 1 ships a firewall with everything but port 80 turned off, and no tool to configure it is installed. You have to go to "Add Windows Components" and install the "Security Configuration Wizard" and then run it. Once you have run it, (and it is fairly easy), the ports are opened up and SMTP and POP3 work.

Nope, that's not it, Actually that was my first assumption...

I know that Windows XP with Service pack 2 has a firewall but I don't think Server 2003 does, and there is no indication of one running, not in the system tray, not in the task manager, nor do I see evidence anywhere on the machine that there might be some tools to manage one, ie stop, start, configure etc. No mention in Control panel or Administrative Tools.

I'm a longtime *nix guy and am fairly comfortable "over there" although I am a developer and not a sysadmin, mostly J2EE stuff.

I recently got the Microsoft "Action Pack" as a partner. It has legit licenses for a bunch of Microsft software for development/evaluation purposes. I decided to install Windows Server 2003 - the first time I have ever installed a Windows Server.

I decided to install...
