Cannot start the debugging process on the Web Server

Previously, vs2005 was installed on the new computer and used for web development. Because vs2005 uses integrated lightweight Web service testing by default, this problem was not encountered, after installing vs2003 today, I got all the projects on the old computer and tried to debug them on the new computer.ProgramIt must be nice. When I started a web project and was preparing for debugging, I jumped out of a bug "I cannot start debugging on the Web server, and I didn't configure Asp.net as debugging". Later I found that, you have not created this project in IIS. For details, go to Control Panel> Administrative Tools> Internet Information Service> Find your project> Properties> virtual directory, the following is an <Application name> followed by a <button>. If it is deleted, it indicates that it has been created. If it is created, click the button to delete it and save it, after debugging, the system jumps out of "cannot start debugging on the Web server, without integrating windows Verification" and finds the problem. The specific operation is as follows: right-click "my computer"-> "management"-> "services and applications"-> "Internet Information Service Manager"-> "website"-> "default website "-> "properties"-> "Directory Security" tab-> "authentication and access control block"-> "edit"-> select "Integrated Windows Authentication ", okay, let's debug it. Everything is done...
