That sounds like a rather dirty bit of MS behaviour, though it could be a bug.

My first reaction is "if it isn't connected, it can't"; my second is that perhaps it tried to validate your licence, couldn't, and has gone into some kind of restricted mode (syn sulk). Curiously most of the hits I get looking for "not connected" suggest that Windows will report a failure to connect.

Is there any possibility that it may have connected via WiFi without your knowledge?

I've always been sceptical about Windows in "mission critical" situations, but then I guess with my background I'd inevitably have that view. Despite having actually used Windows in such a situation. I get more uncomfortable the more MS try to tie my hands.

CNC itself is outside of my knowledge-space. I note that LinuxCNC has a reasonable userbase and it would get away from Windows, which might sole the problem, but might equally raise a whole new set of problems. Might it be worth talking with your CNC person about it?
