Check your firewall. You will have to open TCP Port 88.
Part 4: Opening Up to the Outside
World
Windows Firewall blocks the World Wide
Web Services port by default (Port
80). With this port blocked, other
machines cannot connect to your web
server. This severely limits the
scope of potential web site viewers.
So, in order to show your new web site
and server to the outside world you
must add an exception to the Windows
Firewall.
Click Start and type firewall into the Search bar and press enter.
(Note: Make sure you select Windows
Firewall and not Windows Firewall with
Advanced Security)
Click Change Settings
Click the Exceptions Tab and Scroll to World Wide Web Services
(HTTP).
Click the check box and click OK.
Now your machine is accessible to the
outside world. You can connect to
your machine by typing in the IP
address of your server into another
machine’s web browser.
