Testing Lync 2013 Ports
 I have written the following PowerShell scripts based on the great work of Original Author: Boe Prox   (https://boeprox.wordpress.org).   The scripts simply check and report on all required ports between Front End, Edge Server and Reverse Proxy. Each script should be run on the corresponding server:   From Front End TO Edge   From Edge TO Front End   From Reverse Proxy TO Front End   I hope these are 1/2 as useful to you as they are to me :)
