Hi,

This is solved by installing “Windows Identity Foundation 3.5” on Windows Server 2012.
This can be found in Windows Features installation or easy install with Powershell: “Install-WindowsFeature”.

I just wanted to add the following. if I try to directly access the back end ecp directory I get the error below. I have another test server in a different domain and I can access the back end ecp directly. maybe this error + the error above for the front end ecp directory will help us narrow this down:

Current user: 'Administrator'
