When you try to create a new Microsoft ASP.NET 1.1 application after you change the script mapping of the existing ASP.NET 1.1 Web application to ASP.NET 1.0 on a Microsoft Windows Server 2003-based computer, you may receive the following error message:
The Web server reported the following error when attempting to create or open the Web project located at the following URL: 'http://localhost/822319ev1'. 'HTTP/1.1 500 Internal Server Error'.
This issue occurs because Windows Server 2003 does not allow two versions of ASP.NET to run in the same application pool.
To work around the problem, do one of the following:
Create a New ASP.NET 1.1 Web Application
Configure the Script Map of the Application to ASP.NET 1.0
Create a New ASP NET 1.1 Application
