Actually it can work with domain users just fine.
Been running for well over a year, however after running windows updates just now, it seems to not be working anymore
Will probably try a repatch.
Repatch didn't work... ran the install.cmd and it said "Patched Already ,Config Editing..."
Trying to log on another user now prompts to kick first user.
The MS update 2984972 will break this patch.
Until the patch on this blog is updated, you can roll back MS patch 2984972 by doing the above... (make sure you don't need restricted admin logons support2.microsoft.com/kb/2984972)
