Before you deploy Office Communications Server, you must prepare Active Directory Domain Services (AD DS). Active Directory preparation includes schema preparation, forest preparation, and domain preparation. You perform the Active Directory preparation step only during an initial deployment. This step is not repeated when you add servers or pools to the deployment. For details about Active Directory preparation, see Preparing Active Directory Domain Services for Office Communications Server 2007 R2in the Office Communications Server 2007 R2 deployment documentation.
