I have a Windows 2003 Server which was running on a Windows 2000 domain but the DC failed recently and is no longer functioning/available - there was no DBC in place so I now have a network with two servers, one running Win2k3 and another running Win2k8 both of which are essentially functioning as Workgroup servers for the network. &nbsp;I'm currently preparing a 2012 R2 Server to be a DC which I plan to add the two above servers to, and then promote the 2008 server to BDC. &nbsp;<br />
My main question is, is there any issue adding a 2003 server to a 2012 domain? &nbsp;And, specifically, I'm currently installing AD on the 2012 server and I'm not sure what to set the forest functional level to - I'd appreciate any tips/suggestions. &nbsp;Thanks.

Add a Win2k3 server to a new Windows 2012 domain

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Windows Server 2012

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
