first of all , if you use IIS you must either turn it off or change the port value of it, but iis mostly makes problems on vista when its about website hosting.

Second, i suggest you try WAMP or XAMPP , they are really good in this case. Then make sure that you have opened the required port(s) to run WAMP or XAMPP and host your own website. And you must open port 80.

NOTE that if you don't got a router you don't have to open any ports at all.

When using WAMP you got a WWW folder where you place your website in. When using XAMPP you got a HTDOCS map for it.



Tell me if you need more help.
