Configure DFS file storage for Lync Server 2013


Topic Last Modified: 2016-05-23

Lync Server 2013 supports using file shares on a Distributed File System (DFS). For details about DFS for Windows Server 2008, see the DFS Step-by-Step Guide for Windows Server 2008 at use a DFS, Lync Server 2013 requires the following:

  • Namespaces are domain based

  • All namespace servers are running a minimum of Windows 2008

Lync Server 2013 setup requires that permissions on shared folder allow full access to Administrator. Lync Server 2013 will then use NTFS file permissions to ACL the folders. Inherited DFS share permissions will not be used to restrict access.

For more details about File Share requirements, see File storage support in Lync Server 2013 in the Supportability documentation.
