To verify that the ASP.NET version 2.0 ISAPI filter have been set up correctly
1 Click Start > Settings > Control Panel > Internet Information Services.
2 Expand the local computer node which is usually your computer name and expand Web Sites.
3 Right click the Web Sites folder and select Properties.
4 On the ISAPI Filters tab, make sure the list contains an entry for ASP.NET_2.0.50727.42. If it is present, ASP.NET has been installed correctly, and that you can exit IIS.
If ASP.NET is not present, it is possible that the .NET Framework has not been installed or IIS was installed after the .NET Framework. If IIS was installed after the .NET Framework, there might be a problem with script maps, which you can repair with the ASP.NET IIS Registration tool. Typically, Aspnet_regiis.exe tool is in:
C:\windows\Microsoft.NET\Framework\v2.0.50727
However, before running this tool, you should consult with your Systems Administrator and read the documentation at the Microsoft website below:
