Forest preparation creates Active Directory global settings and objects and Active Directory universal groups for use by Microsoft Communications Server 2010, and grants suitable access permissions on the Active Directory objects. For a description of the universal groups and the global settings and objects created by forest preparation, see Changes Made by Forest Preparation.

Forest preparation also creates objects that contain property sets and display specifiers used by Communications Server 2010 and stores them in the Configuration partition.

Ensure that schema preparation changes have replicated to all domain controllers before performing the forest preparation procedure. If replication is not completed, an error occurs.

If you are performing a new Communications Server deployment, you must store global settings in the Configuration partition. If you are upgrading from a previous version of Communications Server and you still store global setting in the System container, you can continue to use the System container. However, if you are upgrading to Communications Server 2010 from Microsoft Office Communications Server 2007, we recommend that you move global settings to the Configuration container before migrating to Communications Server 2010. For details, see "Migrating Global Settings Container" at http://go.microsoft.com/fwlink/?LinkId=185227.

You must be a member of the EnterpriseAdmins or DomainAdmins group for the forest root domain to perform this procedure.
