simple .NET project does not work

Hi

After installing IIS 8 on Windows Server 2012 (including features .NET 3.5 and 4.5) the simplest .NET website (empty Visual Studio 2012 website with one only Default.aspx file) does not work in local folder wwwroot. AppPool runs with .NET Framework 4 and integrated managed pipeline mode.

- Testing the site in the browser with 'http://hostname' shows the error HTTP Error 403.14

- Testing with 'http://hostname/Default.aspx' shows the error HTTP Error 404.3

Thanks for your advice.
