I have setup Portal using AD and Windows Authentication. Everything is installed on a Server 2012 R2 machine.
The problem is, I cannot get the login to work from a Windows 2012 machine. For some reason it does not seem to pass the credentials correctly. It will just keep challenging me with a login form, over and over
Everything works just fine when connecting from a Windows 2008 machine. This is happening with multiple sites and from every Windows 2012 R2 Server. I cannot find anything that describes a setting that needs to be changed on 2012 that does not need to be changed on 2008.
Any thoughts? Basically cannot setup to use single sign on, unless I only connect from 2008 machines
