You cannot add a domain controller as a node in a Windows Server 2012 failover cluster environment

Applies to: Windows Server 2012 StandardWindows Server 2012 StandardWindows Server 2012 Datacenter

Symptoms


When you build a Windows Server 2012 failover cluster environment, you cannot add a server that has the Active Directory Domain Services (AD DS) role as a node.

Cause


We do not support combining the AD DS role and the failover cluster feature in Windows Server 2012.

Status


This behavior is by design.

More Information


Although we do not recommend this, you can enable domain controllers as a cluster node in Windows Server versions earlier than Windows Server 2012. However, starting with Windows Server 2012, we no longer support this configuration.
