Prerequistes for Remote Debugging Web Applications
With the Visual Studio debugger, you can debug a Web application transparently on the local computer or a remote server. This means that the debugger functions the same way and allows you to use the same features on either computer. For remote debugging to work correctly, however, there are some prerequisites.
Visual Studio remote debugging components must be installed on the server you want to debug. For more information, see Setting Up Remote Debugging.
By default, the ASP.NET worker process runs as an ASPNET user process. As a result, you must have Administrator privileges on the computer where ASP.NET runs to debug it. The name of the ASP.NET worker process varies by debug scenario and version of IIS. For more information, see How to: Find the Name of the ASP.NET Process.
