I want to test my software's SSO, so I am trying to configure ActiveDirectory on Windows Server 2012, following this tutorial.
At "prerequisites step", the window is supposed to look like:
but unfortunately I get an error:
Sorry for the Japanese, it says:
x The prerequisites check for the domain controller upgrade failed. The certificate server is installed. i The prerequisites check is over. x One of the above failed. Please correct and retry.
It seems that ActiveDirectory is already installed, but not configured.
Is there another way to enter the forest/domain name details, apart from this wizard?
Or should I uninstall ActiveDirectory, then restart the tutorial?
