Unable to start debugging on the web server. You do not have permission to debug the application. The URL for this project is in the Internet zone.

After I upgrading Internet Explorer, I got the following message that I cannot debug in visual studio:

Unable to start debugging on the web server. You do not have permission to debug the application. The URL for this project is in the Internet zone.

This is quite strange. Then I start granting permissions, iisreset… but nothing works.

Finally I found that there’s a configuration in IE made this bad thing:

In Internet Options –> Internet –> Custom Level… –> User Authentication –> Logon.

You need to change the “Automatic logon only in Intranet zone” to “Automatic logon with current user name and password”.

Then, everything works again. Really don’t know how MS made the default option.
