Weird things can happen. Not sure what my setting was pre reset of Windows but it did work. Unrelated issues forced me to reset the OS and suddenly could not access shares.
Found the policy setting and changed it to Enabled and could then access the shares again.
Possibly related to "reset" functionality with Windows 10. Don't know if the same issue would occur after clean install of Windows 10 but Windows 10 patching have not been very successful lately.
Since I only have one W10 box,and there's been no need to mess with it:
(Also, we moved and that box isn't here yet. )
What do you mean by "reset function"? Are you talking about rolling the system back, or a "reset to factory defaults" in an OEM build?
Also, what build # are you using?
