Hi Written
My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.
Which version of Windows 10 is installed on these affected clients?
Sorry for the inconvenience of having to suggest the re-route, but Technet has a lot of experts there that know the ins and outs of enterprise issues; especially domain configurations for clients, Windows 10 deployment and migration. So, they will be better able to diagnose and determine whats triggering the prompt in a managed environment.
Thanks for your corporation.
