So, you have numerous Win 10 computers and a Samba share, but only one 
Win 10 computer is having a problem. At a guess, I wouldn't think this 
is a Samba problem, but that there is something wrong with the 
particular Win 10 computer. Is it running the same version of Win 10 as 
the others ? is it setup the same as the others ?

If everything appears to be the same, then you need to check what 
updates are installed (are they all the same ?). You may have to dive 
into the registry.
