Script for automating desktop logoffs in Horizon.

This script will let users know that there desktop will restart after 3 days if they don’t logout. It checks after 3 days and anyone who’s session is less than 5 days old won’t be restarted and everyone else will.

This requires the AD powershell module that gets installed with the AD RSAT tools and vmware hv helper module
