When Internet Explorer is prompted to save .aspx pages when running , your web server has lost its mappings to ASP.NET.

To remedy this situation, you must rebind ASP.NET to IIS.

This can be accomplished by running the following steps from the web server:

1. Open a command prompt

2. Change to the following directory (or whatever version of the .NET Framework you are using): C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322

3. Run the command "aspnet_regiis.exe -i". This may take several minutes and will report the success/failure of the process.

If this does not work, you may need to reinstall IIS.
