You can lock and unlock user PINs by using Windows PowerShell and the Lock-CsClientPin and Unlock-CsClientPin cmdlets. You can run these cmdlets either from the Lync Server 2013 Management Shell or from a remote session of Windows PowerShell. For details about using remote Windows PowerShell to connect to Lync Server, see the Lync Server Windows PowerShell blog article "Quick Start: Managing Microsoft Lync Server 2010 Using Remote PowerShell" at http://go.microsoft.com/fwlink/p/?linkId=255876.
