Lately I’ve been having issues where my drive mappings fail when rebooting my Win 10 PC. I’ve been resorting to rebooting my MyCloud to correct these issues.
I suspect something is happening to SMB on the MyCloud. This is the error I get when trying to access a share.
Also checking the logs on MyCloud I see this. I’m not sure if it’s meaningful. Last few lines from /var/log/log.nmdb. My Bolding.

Could this be a case of Win 10 taking over as master browser.
I’ve done a lot of searching on google with these symptoms but found nothing conclusive. One interesting post mentioned that Win 10 might take over as SMB master browser from MyCloud SMB. Not sure if that is the issue here.
What happens if you attempt to access the My Cloud, or map the My Cloud Share using the My Cloud’s IP address? Do you have the same problem?
In the following thread there is some discussion on SMB in Windows 10 when Microsoft borked the SMB2 a while back. May want to take a look and see if anything in there might help. There is a suggestion in that thread to configure the router as the “master browser” for SMB if the router supports such an option.
Thanks for that. Since this issue seems to happen randomly (after a reboot of my PC), the next time it happens I will look at a few things. I’ve never checked to see if my MyCloud shows up under network in Windows Explorer.
OK, it happened again. So I tried with the IP address and it worked. Note that the WD MyCloud isn’t showing in Network on Windows explorer when I have this problem.
Also this is only a work around. It doesn’t get to the root cause of the problem.
Have you updated your Windows 10 PC with ALL of the latest Windows 10 updates?
Are you running a third party Firewall software program? Or have you modified the Windows Firewall to block local network access to the My Cloud? Have you enabled NetBIOS over TCP/IP in Windows 10? Have you enabled local network sharing within Windows 10? Have you installed all of the latest Windows 10 updates?
See the link I posted previously that has this and other Windows 10 suggestions when one has issues accessing the My Cloud under Windows 10.
As a test, try setting the Windows 10 SMB to SMB 1 or SMB3 and see if that works around your issue. See the link I posted earlier in the thread for directions on how to change the Windows 10 SMB version.
Problem is back. I booted my PC this am and all mapped drives were big red X. Clicking on them resulted in the original error message.
Did the Get-SMBConnection command in powershell and Mycloud didn’t show up. SSH’d into mycloud and ran TOP. Didn’t see nmb or smb. Started SAMBA and my mapped drives work. Also ran Get-SMBConnection and mycloud shows up.
I’m not sure this is the same issue, as before, if I started SAMBA, it didn’t fix things.
SAMBA was running when MyCloud last booted. However this morning when I booted my PC it apparently wasn’t. I will be checking logs on MyCloud to see if I can determine why SAMBA tasks weren’t running.
