Lync 2013 Management Shell black screen issue

Lync server 2013 management shell often shows black screen when you launch it from Lync Front End server.

I am assuming that this is a Windows Server 2012 R2 ‘bug’ as I have never seen it before on win2k12 or 2k8R2 environments.

This usually comes and often drives fresh techs crazy although its resolution is pretty simple.

Resolution

if you open Lync Server Management Shell properties and check the target you will find this

C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -noexit -command "cd $env:UserProfile; Import-Module 'C:\Program Files\Common Files\Microsoft Lync Server 2013\Modules\Lync\Lync.psd1'

which is clearly missing the double quote (") at the end, just add double quote and restart the shell it will work like a charm.
