When you use Visual Studio .NET 2002 to create a new Web project, and you connect to Microsoft Windows Server 2003 as the Web server, a Web Access Failed dialog box appears and you receive the following error message:
The default Web access mode for this project is set to file share, but the project folder at 'http://localhost/WebApplication1' cannot be opened with the path 'c:\inetpub\wwwroot\WebApplication1'. The error returned was:
Unable to create web project 'WebApplication1'. The file path 'c:\inetpub\wwwroot\WebApplication1' does not correspond to the URL 'http://localhost/WebApplication1'. The two need to map to the same server location. HTTP Error 404: Not Found
This problem occurs because Microsoft Internet Information Services 6.0 (IIS) blocks all file name extensions that are not explicitly mapped. By default, the .tmp file name extension is not mapped on IIS 6.0 for security reasons.
During the process of creating a Web project, Visual Studio .NET 2002 tests to confirm that the URL and the UNC path match. To do this, Visual Studio .NET writes a file that has the .tmp file name extension to the server, and then requests this file from the server through an http request. Because the .tmp file name extension is not mapped on IIS 6.0, IIS returns HTTP Error 404. This causes Visual Studio .NET to return the error message described in the "Symptoms" section.
Note This problem does not occur when you use Visual Studio .NET 2003 because this version uses a file that has the .htm file name extension for this process.
