Deploying Office Communications Server 2007 R2 in a Multiple Forest Environment

Topic Last Modified: 2009-11-20

A multiple forest topology is often used in enterprises that have a need for multiple forests in Microsoft Active Directory directory service Domain Services to provide security or organizational boundaries. This document assumes that you have decided upon a multiple forest topology. For more guidance about when a multiple forest topology is appropriate and how to deploy, see the Microsoft Windows Server operating system documentation. 

To support a multiple-forest environment, Microsoft Office Communications Server 2007 R2 must be deployed in only one forest in your topology, which is designated as the central forest or the resource forest. Deploying and synchronizing Communications Server 2007 R2 across multiple forests is not supported.
