The Active Directory Domain Services on-premises topologies that are supported by Lync Server 2013 are as follows:

Lync Server 2013 does not support single-label domains. For example, a forest with a root domain named contoso.local is supported, but a single-label 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 2013 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 for on-premises deployments, see Active Directory Domain Services requirements, support, and topologies in the Planning documentation.
