SYMPTOMS
When you try to create a project or open a previously created project, you may receive the following error message:

Visual Studio .NET has detected that the specified Web server is not running ASP.NET version 1.1. You will be unable to run ASP.NET Web applications or services.



CAUSE
When you create or open a project in Microsoft Visual Studio .NET 2003, Visual Studio .NET 2003 makes an HTTP Web request to determine the version of the .NET Framework that is on the Web server. Visual Studio .NET 2003 calls the http:// /get_aspx_ver.aspx page. If you receive the error message, the default Web site is using Forms authentication, and the request is redirected to an .htm page. Therefore, the request for the .aspx page is never made, and Microsoft Internet Information Services (IIS) cannot return the version information.



RESOLUTION
To resolve this problem, use the location tag to stop Forms authentication from redirecting the request. To do this, add the following code to the Web.config file:
