I searched enough but couldn't find a solution. I have a ASP.NET Intranet app at Windows Server 2008 IIS 7.5 with windows authentication - this all work great.
I have been trying to migrate it to Windows Server 2012. I have already installed Windows Authentication role for the server and already enabled the windows authentication for the web site.
The application seems to be working fine for my account but if anybody else try to connect they get windows login popup.
