Mapping Drive MyCloud EX2 Ultra

Can you ping your NAS by IP?
Can you access the admin UI using the browser?
Can you see your NAS as a storage device when you click on Network in Windows Explorer?
If yes to all 3 questions and you cannot access it through “\\MYCLOUDEX2ULTRA” or “\\<IP_ADDRESS>” you might have the same issue as I experienced.
Check this thread I gave 2 ways of solving the issue.http://community.wd.com/t/ex2-ultra-have-tried-everything-but-not-visible-on-windows-10/249329
Basically it boils down to adding windows credentials for your NAS or forcing windows to accept guest logons (I added windows credentials on mine).
Hope it helps. Let us know if that solved the issue.
