@Tom-Elliott THIS IS NOT SOLVED! I am using the production version of 1.2 with the client that came with server 1.2. The client works great on ALL PC’s in my environment until you run a W10 version upgrade through Windows update, then it breaks the client.
I did try to upgrade to the NEW client, which obviously did not work.
I am now trying to load Windows 10 from scratch, do all the updates - and THEN install the FOG client.
