Well, usually I will store my web project in default web folder, due to some reason, I want to create the project on IIS instead, allowing remote access with the afford of helping in testing.

When the debug started, Visual Studio show error message

Unable to start debugging on the web server. Debugging failed because integrated Windows authentication is not enabled. Please see Help for assistance.

To fix the annoying problem, simple have Visual Studio 2005 service pack 1 installed, and apply the hotfix kb937523 . After applying the update it works!
