I have not yet tested if doing this demotion procedure breaks any basic functionality of the product, but at first blush, it appears not, as backups do appear to continue to work fine. This first test opens the door to my next recording sequel videos, hopefully showing:

• install WS2012E (Windows Server 2012 Essentials)
• remove AD Domain role and reboot
• install client connector on PCs
• determine if backup and shared folders functionality still appears to work fine
