Supported Active Directory Topologies

Communications Server 2007 R2

Topic Last Modified: 2009-05-07

Office Communications Server relies on Active Directory Domain Services (AD DS) to store global settings and groups necessary for the deployment and management of Office Communications Server. Office Communications Server 2007 R2 supports the same Active Directory topologies as Office Communications Server 2007.

Office Communications Server can be deployed in a locked-down Active Directory environment. For details about the special considerations involved in deploying Office Communications Server in a locked-down environment, see Preparing a Locked Down Active Directory Domain Services in Preparing Active Directory Domain Services for Office Communications Server 2007 R2 in the Deployment documentation.

This section identifies the Active Directory topologies supported by Office Communications Server 2007 R2. For details about operating system and domain functional level requirements for AD DS, see Environmental Requirements.

For details about supported Active Directory topologies, see Active Directory Domain Services Requirements in the Planning and Architecture documentation.

For details about preparing AD DS for Office Communications Server installation, see Office Communications Server 2007 R2 Active Directory Guide in the Deployment documentation.

Office Communications Server supports single-forest and multiple-forest Active Directory environments.

The Active Directory topologies supported by Office Communications Server are as follows:

  • Single forest with single domain
  • Single forest with a single tree and multiple domains
  • Single forest with multiple trees and disjoint namespaces
  • Multiple forests in a central forest topology
  • Multiple forests in a resource forest topology
