There is bug in build Windows 10 Update 1511 (10586). In Windows Explorer, Windows computers on a Wired network (except the master browser computer) cant see any other Windows computers on the network.
I have been trying to resolve the issue without luck so far. What I have found is:
If I turn off all the computers, and start computer no.1 first, it becomes the Master Browser (as it should) and can see/access all Windows computers in Windows Explorer. If I then turn on computer No.2 it wont be the Master Browser, and it cant see/access any other Windows computers on the network, and it's the same for computer 3, 4, etc when I turn them on.
If I turn off all the computers again, and start no.2 computer first, it becomes the Master Browser and can see/access all Windows computers on the network in Windows Explorer. If I then turn on computer No.1, 3, 4 etc they wont be the Master Browser, and it cant see any other Windows computers on the network.
The is repeatable for any of the computers on the network, The computer that's tuned on first, is the master browser and and can see/access all other Windows computers on the network in Windows Explorer. Any computers turned on after the first computer cant see/access other Windows computers on the network In Windows Explorer.
It also happens if the Master Browser computer is rebooted. When it restarts it's no longer the Master browser, and cant see/access any other Windows computer on the network, but the computer that has become the Master Browser can now see/access the other Windows computers on the network.
In summary, IMO this Windows 10 update 1511 has a major Ethernet/Master Browser Bug that is a 'show stopper' for Windows computers wired networks.
BTW setting up a Home group on a network with this bug works fine, and all computers joined to the home group can see and access all the other home group computers.
I can also see the NAS and network printer on all computers in the Windows Explorer network screen, I just cant see any other Windows computers on the network, except on the Master Browser computer.
Here are the error messages that appear in Windows 10 event viewer for computers that cant see other computers on the network:
