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 http://go.microsoft.com/fwlink/p/?linkid=3052&kbid=300684.
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.
