I have a freshly installed Server 2012 R2 Core Edition with all of the latest updates as of today. I did the following:
- Changed name to DC6
- Joined it to the existing domain.
- Logged in as domain admin.
- Set fixed IP address & set DNS servers to other DNS servers already on the network.
I then installed the AD DC via Server Manager from my computer and that went through fine. I then logged into the server itself and ran the following command:
Install-ADDSDomainController via powershell and answer the commands as requested for the current domain and safe mode administrator password. I get the following error:
Verification of prerequisites for Active Directory preparation failed. The specified user does not have SESecurityPrivilegeEnabled.
I ensured that domain admins (I'm logged in as a domain admin) are in the local admin group and that hasn't helped. NOTE: I haven't had any problems adding domain controllers in the past, only with this Server 2012 R2 version. I'm currently running Server 2008 R2 DC's at the 2008 forest level.
Anybody have any ideas?
