Let me start with a history of how I came to find this information. This history should provide a good example of why this process may be necessary for you.
My organization is part of a state-wide Active Directory system. As a sysadmin for a single, smallish county among 58 counties, my clout to have the state upgrade its system is non-existent. My powers are limited to being an Organizational Unit administrator for my county's OU.
Our county's web security service (a series of proxies run by Cisco) recently disabled support for all versions of SSL and TLS 1.0. 200 users were suddenly unable to use the web. Active Directory 2003 doesn't have the necessary GPO settings to enable TLS 1.1 and 1.2. I had to be tenacious with Microsoft Support that there MUST be a way to get these GPO settings in my 2003 environment. It took escalation to a Tier III Microsoft support engineer to find this information.
If you're still running a Windows 2003 Domain Controller, then you won't have the proper options in that GPO. Here is the way to get Windows Server 2012 GPO's and GPO options in a Windows 2003 Domain:
1. Have a Windows Server 2012 member server.*
2. Use the Server Manager to “Add Roles and Features”
3. Add the Active Directory Domain Services feature, and restart.
4. Copy all of the files inside your Windows Server 2012’s C:\WINDOWS\PolicyDefinitions\ folder to a Windows 2003 Domain Controller’s C:\WINDOWS\SYSVOL\domain\Policies\PolicyDefinitions\ folder.
5. Launch the Group Policy Management Console on the Windows 2012 server.
6. Right-click your domain, and select, “Change Domain Controller”. **
7. Select “This Domain Controller:”, and click on the domain controller that you copied the Policy Definition files to. Click OK. **
8. You will now be able to configure all Windows 2012 Group Policy Objects from your Windows 2012 Member Server, and your domain will push those policies to the appropriate users and/or computers.
* Windows 8.0 or 8.1 will also work, but before step 2, you have to install Microsoft’s Remote System Administration Toolkit (RSAT). Also, with Windows 8.x the “Add Roles and Features” option is in the Control Panel/Programs and Features. Click “Turn Windows features on or off” in the upper left quadrant of the window.

** The policy definitions will eventually replicate to your other domain controllers eliminating the need for steps 6 & 7. Those two steps are only to get you going as soon as possible before replication occurs.
