Unable to Start Debugging on the Webserver. The Project is not configured to debug

Hi,

You get this error "Unable to start debugging on the webserver. the project is not configured for debugging" occasionally when your aspnet account doesnt have debug permissions.

This can happen, if the vs.net installation was not made properly or some reasons when the aspnet account fails to have the necessary rights.

To resolve this, re-register the aspnet account with the IIS, by typing the following command from the command prompt:-

%windir%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i

Note: Change the v1.1.4322 to v1.0.3705 if you are using .net 1.0 version.  This should resolve the problem.

I have been receiving various queries regarding different versions of this error “Unable to start debugging...“.  This error appears due to many reasons other than the above mentioned.

For a complete list of solutions, please check http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vstechart/html/vsdebug.asp

You need to make sure your authentication mode = "Window" and also make sure your application folder can run scripts to start debug.

For anyone else who might read this...

I resorted to uninstalling and reinstalling IIS from my version of XP Pro (not such a big deal if you havent loads of virtual roots). I then ran aspnet_regiis.exe as detailed above, and all this whilst logged on as Administratpr

After this i was able to debug again.

If you are running Visual Studio 2003 (or ASP.NET v1.1) you should setup IIS to use ASP.NET v1.1 and not ASP.NET v2.0, go to IIS, click properties on the virtual directory and select the ASP.NET, and select the required ASP.NET version.

You might also try creating a new web app and if it debugs, then there's nothing wrong with IIS. Try renaming your app and re-creating it, copy over the files to the new one and do any quick fixups. Worked for me.

Try enabling "Integrated Windows authentication" mode in Authentication methods of IIS for the project virtual directory. This worked for me.
