>> FDResPub <<
The problem seemed to have cured itself, but it's back.
I turned on all of the services listed in the response on the first page of this (very long) thread, but that didn't work.
So, I set up a task scheduler event for FDResPub as suggested in the above post, but, it does not work, including restarting the computer.
fwiw, when I was presented with a login credential screen with my current login as the user, but, when I filled in the password, I received the message that "The specified Account name is not valid"
Turns out that you have to manually add the <computername><username>
Note
-====================-
I just purchased a second Win10 computer for my wife, and confirmed that the problem is the same with that computer as well. Again, I can connect to this Win8.1 computer using another Win8.1 computer on the same network.
Help (again)

This thread is specifically for windows 10 network, not a mixed of windows 8.1 and Windows 10.
I assume all you PCs are on the same workgroup.
See my first entry on page 18 to setup the FDResPub Restart in Task scheduler.
All the other settings should be just the windows 10 defaults for File sharing on Private network, no need for any special settings.
When you have the problem described in this thread the PC is not visible to itself on the network not just from other PCs. This only affects Ethernet connections, never seen this problem on Wi-Fi.
