Hi All
I was just reading this thread and it reminded me of a known issue in Windows when you have connected too many USB Ethernet adaptors and they are stored in the registry. You get weird behaviour of the connection working but unable to connect to network shares.
It was a problem in Windows 7, and not sure if it has been solved for Windows 10. There is a thread on it here:

And here:

Worth checking if this is the issue, especially if you use hot desking, so will end up with many different USB Ethernet entries in device manager, if you move desks a lot.
