If ASP.NET is not shown in this page somehow the installation of ASP.NET did not register itself in IIS. To correct this, use the tool aspnet_regiis.exe in the .NET Framework installation folder to correct this situation. Please refer to the Microsoft documentation on how to use this tool, e.g., http://msdn2.microsoft.com/en-us/library/k6h9cz8h(VS.71).aspx.
