In Late October 2023 after a Windows Update We found that we could not see our Western Digital NAS WDPR4100 and WDEX4100 units. We did everything that we could to solve the issue but the solution turn out to be very simple. All we had to do was to log onto our PR4100/EX4100 units and turn on the IPv6 protocol and the units appeared in our Windows 11 network environment. We could always map a drive or access the units but they would not be shown in the Windows 11 neighborhood. This allowed the NAS units to be visible in Windows 11.

If you have an old Windows 10 PC on your network, you will need to turn on SMB 1.0 in order for it to be seen. You will need to turn SMB 1.0 on the Windows 10 PC, on the NAS unit (or server) that acts as the DNS Server for your network and on the PC that you want to see the Windows 10 PC on.

The strange thing is that I had to turn SMB 1.0 Client on to see every computer and NAS unit on the network. Otherwise I could randomly see computers on the network. We have a mix of Windows 11 Pro, Windows 11, Windows 10 Computers and NAS Units. Of course if I used a network scanner I could see every computer, Printer and NAS unit on the network. The Windows network is still a little shaky and sometimes does not make a lot of sense...
