Adding Windows Server 2012 DC in an existing Windows Server 2012

As part of the series of Windows Server 2012 deployment, I will be showing us how to promote a Windows Server 2012 member server into a domain controller in an existing Windows Server 2012 R2 domain. Lets begin the journey 🙂 Exciting.

Requirements:

– Ensure your Forest/Domain functional level is minimum Windows server 2003
– Ensure that you have an existing Windows Server 2012 R2 Domain Controller in place
– Ensure you assign a static IP address to the server. See here for steps
– Ensure you have a domain account that is a member of “Enterprise Admins group“, “Schema Admins group” and/or “Domain Admins group“. This is required for the installer to run the adprep tool

Setup Guide:

– Log into the newly installed Windows Server 2012, click on the server manager icon to launch the server manager screen. Click Manage/Add Roles and Features
