ActiveDirectory domain service wizard: Prerequisites check for domain controller upgrade fails

Question

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?

Solution

If you have already added the Active Directory Certificate Services before promoting it to a Domain Controller, remove the Certificate Services role, and then add the AD DS role again.

If the "Add Roles and Features" wizard does not allow you to remove Active Directory Certificate Services" (checkbox is greyed out), then you can remove it using the following PowerShell command:

Remove-WindowsFeature -Name AD-Certificate

Exactly! Remove ADCS role, add ADDS role, add ADCS role again
