We have decided to Demote the new server and create a domain and migrate everything over. &nbsp;The work outlined in the blog is spot on but a the end of the day we were moving the problems over too so we decided to start fresh. &nbsp;Thanks for all the comments.

I recently upgraded a 2003 DC to 2012R2 DC. &nbsp;I was abele to move all FSMO roles and Schema role to the new DC with out a problem. &nbsp;When I went to demote the 2003 DC it did not recognize the 2012 controller and in turn notified me it was the last DC in the Forest. &nbsp;No big deal, I'll just remove it, except when I shut the 2003 DC off I cannot join anything new to the domain. &nbsp;When i turn it back on I can join new items Domain.

Upgrade 203DC to 2012DC

I recently upgraded a 2003 DC to 2012R2 DC.  I was abele to move all FSMO roles and Schema role to the new DC with out a problem.  When I went to demote the 2003 DC it did not recognize the 2012 controller and in turn notified me it was the last DC in the Forest.  No big deal, I&#39;ll just remove it, except when I shut the 2003 DC off I cannot join anything new to the domain.  When i turn it back on I can join new items 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 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).

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.
