UPDATE: THIS HAS BEEN FIXED WITH THE RELEASE OF WINDOWS SERVER 8 BETA
In my previous post I went over installing my first Windows Server 8 box.
Since one of my skill sets is Active Directory my next step was to promote this box to become a domain controller.
As noted in the previous post this is an early pre-Beta release so there are going to be features that are not fully developed.
During dcpromo you can select your domain and forest functional levels.
Initially I was ready to go straight to Windows Server 8 levels and why not, it is a lab and we are all learning at this point.
Windows Server 8 Functional Levels selected
Before dcpromo completes a prerequisite check is conducted. As you can see I receive an error
The error is
The specified value '5' is not valid for the argument 'Domain level'
I then went back and changed the functional levels to 2008 R2
Once that is done the promotion did complete and I now have my first Windows Server 8 Domain Controller.
This is a known bug so no reason to report it up the Microsoft chain. Again...this is an early pre-Beta release.
Enjoy and have fun with your new Windows Server 8 Domain Controller :)
