Lync 2013 – SQL Mirroring Permissions & Firewall Requirements

2017-12-07T14:17:12+00:00 March 19th, 2014|Skype, SQL|


When I initially deployed Back End Server High Availability for Lync 2013 I ran into a number of errors which were essentially being caused by the local Windows Firewall on each node and permissions on the witness file share. To make life easier for next time I drew up this quick Visio diagram as a reference of what is required before being able to deploy SQL mirroring via the Lync 2013 Topology Builder or Management Shell.
