I am using Win 10—Windows Explorer does see the drive. I can also access it using my browser—I use WD Smartware to backup my computer; somehow WD backup engine seems to be working in the background, but Smartware does not see it.

WD Smartware does not see or display My Book Drive-(network connected)

There are reports of various solutions, all non-WD related. Google it and see if one works for you.
