I have Windows 10 pro an multiple machines at the house, always is an issue to connect to any NAS.
I have a WD My Cloud 3 TB NAS that Linux and Windows 7 and older versions connect to it without any problems, just works.
Windows 10 Pro I had to install WD Connector to get it to connect reliably, otherwise sometimes it connects fine other times it does not even see the NAS or if its connects it loses the connection and then cant find, or if I'm copying files it errors out.
FreeNas and NasForFree also I can't connect to them from a Windows 10 Pro machine, LOTS of stuff on-line about that......even when people can get it to work along comes a Windows update that hoses the fix.
It's ridiculous.
I had less problems networking my Compaq Deskpro 8086 pc with a hobbyist developed Tcp/IP stack on DOS on my home network than just one Windows 10 Pro pc.
