The fact that you are getting the HTTP Error implies that your web server is running and is not blocked in any way. The resource not found implies that the web server is pointing to the wrong directory.
I tend to run the XAMPP system which installs everything except moodle and as a result I get a little more help (e.g. a web based interface to the MySQL database).
I have been doing things on the web since before it had pictures but I still find setting up a server confusing on occasions.
