Here’s a free Windows PowerShell cmdlet that lets you check the status of Group Policy processing on remote systems. The Group Policy Health cmdlet from SDM Software is a command-line tool that shows Group Policy processing status at a glance using a red-green color scheme—red means an error was returned, and green means processing succeeded. It works on a single machine, all machines in an Organizational Unit (OU), or all machines in your domain and comes with a Help file explaining how to use it. The Group Policy Health cmdlet can be found at SDM’s website
