Windows 10: Computers not showing up on network

I have a network of 5 computers- are on Private Networks, but 4 computers recognize 4 computers but not the 5th, while the 5th computer recognizes all 5 computers. I can't map any network drive to 5th since it isn't recognized on the list. Also, don't know if this matters, but 4 computers (including the fifth one that's not being recognized) are on Private Network 3, while one computer shows up on Private Network 4. Is that a problem and how to fix it? All computers are set to be discoverable. Running v 1709 build 16299.492 on 4 computers (including the one that doesn't show up), and one computer is on v 1803 build 17134.165

No computers show in Network

If we understood it correctly, the computers still do not show the Network tab after troubleshooting computer B. You may be correct that the firewall is blocking the network connection. You can try resetting the firewall settings and see if the issue will
still persist. Follow the steps below:

• On the Search bar, type CMD.
• Right-click the Command Prompt from the search result and select
  Run as administrator.
• Type this command: netshadvfirewall reset and press
  Enter.
• Once you are done, restart your PC.

We will wait for your update about the result.
