Thread:Project:Support desk/PLEASE HELP - Windows Authetication on IIS

I am using IIS 7.5 on Windows 7

I am trying to use the auto_remoteuser extension to enable auto login and has followed the instructions on https://www.mediawiki.org/wiki/Extension:Auth_remoteuser

However, when I disabled Anonymous auth and enable window auth and when I tried to access the my mediawiki site on my firefox it gives me the following error

Not Authorized HTTP Error 401. The requested resource requires user authentication.

When I access my mediawiki site on Chrome/IE, it gives me the prompt and when I entered my domain/username and password, it denies my entry and keep showing me the prompt.

Please help. Thanks!!
