IIS question?

A couple weeks ago I installed easyPHP on my machine and it change the default folder that IIS(localhost looks into). Now I want IIS(localhost) to look in the initial folder that it used to look in(C:\Inetpub\wwwroot). How can I do this? I know it does not do this becuase it pulls the index page from the PHP directory and not the ~wwwroot directory.
