Unfortunately 2012 R2 will only joins 2003 or higher domain. 2000 is just too old. You'll either have to rebuild the domain from scratch or introduce an older domain controller temporarily to bridge the gap.

Sorry should have mentioned that's what we plan to do. Although I do need to know it would join the domain as it has to be the o ly domain controller. That is not a problem anyway S everything else will be decommissioned anyway.

We have a new customer in the Health industry who have a Server 2000 environment, don't ask, consisting of an exchange server, Cluster and Domain controller. All is no longer required and we feel that a small 2012R2 Foundation server will fit the bill. As the license for this is only one domain controller we were wondering if we would be able to join this to the existing domain first then decommission the existing 2000 domain controller. This would make it so much easier to migrate the PC and users etc.<br />
<br />
What do you think, before I have to create a test environment, thanks in advance.

Server 2012R2 Foundation and Server 2000

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

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Windows 2000 is an operating system for use on both client and server computers. It is the successor to Windows NT 4.0, and is the last version of Microsoft Windows to display the "Windows NT" designation. Four editions of Windows 2000 were released (Professional, Server, Advanced Server, and Datacenter Server) that shared a core set of features, including many system utilities such as the Microsoft Management Console. All versions of the operating system support NTFS 3.0, Encrypting File System, as well as basic and dynamic disk storage. The Windows 2000 Server family includes support for Active Directory services, Distributed File System and fault-redundant storage volumes.
