Active Directory Support


Topic Last Modified: 2012-12-04

The Active Directory Domain Services topologies supported by Microsoft Lync Server 2010 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


Lync Server does not support single-labeled domains. For example, a forest with a root domain named contoso.local is supported, but a root domain named local is not supported. For details, see Microsoft Knowledge Base article 300684, “Information about configuring Windows for domains with single-label DNS names,” at


Lync Server 2010 does not support renaming domains. If you need to rename a domain where Lync Server is deployed, you need to first uninstall Lync Server, then rename the domain, and then reinstall Lync Server.

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