Have a WDMycloud device. I can connect locally (ethernet) to the Dashboard ok . But can not map the drive locally to our Windows 10 PC. Can map it ok to the MAC devices.
Have turned on the SMB 1.0/CIFS File Sharing Support ON, in the Windows Features.
WD Firmware = 5.14.105
Log files show
TYPE = SAMBA
Log = CIFS: Authentication for user [GUEST] has FAILED.
