Step-By-Step: Adding a Windows Server 2012 Domain Controller to an Existing Windows Server 2003 network
Sharing knowledge amidst social media
is a passion of mine. I challenge myself to try and spark a
conversation via any of the most widely used social media avenues
available. So when a request for a Step-By-Step post on Active
Directory migration following the previous Step-By-Step post on DHCP Migration,
Pierre, Mitch and I were only too happy to oblige. Before detailing
Active Directory migration, we felt it pertinent to showcase how to add a
Windows Server 2012 Domain Controller to an existing network first.
Migration of Active Directory from Windows Server 2003 to 2012 would be
the next step once this Step-By-Step has been completed successfully.
Prerequisites
Setting Up Domain Controller Fuctionality

Prerequisites
- Download Windows Server 2012 R2. If you plan on completing this Step-By-Step in a virtual lab, it is recommended to download the FREE Hyper-V Server 2012 R2 first.

- Via the Active Directory Users and Computers console, select the domain via the right mouse button on it.
- Select Raise Domain Functional Level and review the Current domain functional level reported
The Domain Functional Level does not need to be raised if the Current domain functional level is reporting Windows Server 2003.
NOTE: Should a lower domain be showcased (i.e., Windows Server 2000), please keep in mind that raising Domain Functional Level is a one time action and cannot be reverted. Remember Windows NT / 2000 Domain Controllers are not supported via this process. - Ensure your profile is a member of the Enterprise Admins group.
- Setup and install your Windows Server 2012 machine
