You have your new GPO perfectly configured and you’ve linked it to your OUs. Heck, you’ve even made sure that your GPO didn’t have any common configuration issues! But now, you have to wait… 90 minutes… plus up to 30 extra minutes (due to the GPUpdate random interval). While you could run around and manually start the Group Policy refresh, let’s be lazy today and start a remote GPUpdate instead!
Note: Technically, the lazy option is to just wait. The lazy but intelligent option is to do it remotely. So, be smart about being lazy and use these three methods.
