Schema preparation is the first step in preparing Active Directory Domain Services (AD DS) for Office Communications Server 2007 R2.
The schema preparation step extends the Active Directory schema to include classes and attributes that are specific to Office Communications Server. It is run once, against the schema master, for each Active Directory forest where you plan to deploy Office Communications Server.
|In a resource forest topology, this step is run only in the resource forest, not in any user forests. In a central forest topology, this step is run only in the central forest, not in any user forests.|
Office Communications Server 2007 R2 introduces some new Active Directory classes and attributes. For a description of all the classes and attributes specific to Office Communications Server, see Active Directory Domain Services Reference.
For the detailed steps and user rights required for this procedure, see Preparing Active Directory Domain Services.
