Before you deploy and operate Microsoft Communications Server 2010, you must prepare Active Directory Domain Services (AD DS) by extending the schema. The schema extensions add the Active Directory classes and attributes that are required by Communications Server 2010.
Communications Server 2010 requires one new class and several new attributes and modifies some existing classes and attributes.
This topic describes the Active Directory schema changes required by Communications Server 2010. It does not describe Active Directory schema changes that were introduced by previous versions of Communications Server. For details about classes and attributes introduced by previous versions of Communications Server, see the ServerSchema.ldf and BackCompatSchema.ldf files. These files are located on the installation media.
The msRTCSIP prefix identifies classes and attributes that are specific to Communications Server.
