I have ASP.NET application with windows authentication. When I browse it from home over VPN (Cisco VPN Client) as a username in the windows identity I get "\" not the credentials from the AD of the server (the same that I am using to connect to the VPN) even though I fill them in the prompt for localhost authentication from the browser.
This only happens with Firefox. In the IE and Chrome after the prompt I get 401.1 Unauthorized page from IIS.
How to make IIS to use the right credentials or the problem is somewhere else?
Any ideas?
