Test the installation/config. Go to C:\inetpub\wwwroot and create a text file, saved as hello.txt. Open the file, then type in "hello world" and save it.
Open your web browser and type in
http://localhost/hello.txt[
^] to see if you see the message.
Deploy your site/pages/etc to the path and you should be good to go. Just having IIS setup doesn't mean there's content there. What is your default document?
Cheers.
