Port 80 should be enought to get connected the the page over HTTP, so it
could be the way you're connecting to the server that might be failing
(FQDN, IP, NetBIOS name). Try connecting to the site via the external IP
address of your machine and see if that works. Also, you mentioned you
could connect to your site via another computer. Was this computer on the
Internet? The reason I ask is some ISPs with high-speed access restrict
certain port requests to their customer's machines to prevent them from
hosting web sites, FTP sites, ect, which could degrade performance of their
connections. I'm making you aware of this just to be sure this is not the
case.
If you're able to get connected to your machine from the Internet and it's
only computers at work going through your firewall that are failing, you
may want to get a NetMon trace of the traffic to see where you're failing.
You can also use utilities such as TraceRT.exe, ping, and Wfetch.exe to
verify connectivity to your web server.

HOW TO: Use Wfetch.exe to Troubleshoot HTTP Connections
