First, thank you for reading the rules before posting ... something most people don't bother to do.
The default page for a server is set in a config file. Usually it's index.html (or another suffix such as htm, php), but an be set as default.html or home.html or anything else desired. In your case index.html is probably the default and home.html is being used as the real home page. If you want people to just see the home.html page in that directory as the default page and not have to worry about all the other site links, then adding a .htaccess file to the directory with a redirect from the index page to the home page would be the easiest way to do it. Do a Google search for [/i].htaccess redirect[/i] and you'll find the instructions for doing this.
