Windows 10: Network of two computers works on one only

I have two desktop computers both running Win10 most current connected by two cables to one Xfinity Modem/Router. Some time ago, I set up a Network on both machines. When I open File Explorer on machine "A", I see both "A" and "B" computers and can access any file on both. However, when I open File Explorer on machine "B", in the "This PC" directory I see the Network folder, but it has no listing of any computer.

What's wrong? Why my Network works one way only? How to make my Network work both ways?

:)

 

One computer cannot access other network computers.


So I've tried every troubleshooting step I know:

• Double checked that Net Bios was enabled
• Ran a bunch of network commands:
  • flushed DNS
  • registered dns
  • pinged and located the named computers successfully
• Reset my router to factory settings

Nothing works when I try to access via explorer. I'm still baffled by the fact that every other computer can access each other AND access this computer. It's just the outgoing connection from this machine that doesn't work.

Any thoughts?

Another question, is this on a home network or a work network? The steps @eidairaman1 listed are always a good first step. If this is on a work network you manage, I'd be much more concerned than the home one. It is possible someone is screwing with you, but malware could also be the culprit.

We suggest creating a new administrator user account by following the steps
here. Make sure to use the same network settings that you used for your other computers, then check if you can connect to the home network. Since you also mentioned that Windows 10 was freshly installed on this particular computer, have you already downloaded
the latest updates? The latest build for Version 1607 is 14393.1715, and 15063.608 for Version 1703. You can check the build version of your computer by following these steps:

• Click Start.
• Type winver and press Enter.

If you don't have the latest updates, you can follow these steps to install them:

• Click Start.
• Go to Settings.
• Click Update & security.
• Click Check for updates.

If that doesn't work, we'd like screenshots of the network and file sharing settings of the computer that doesn't work, and the settings of one of your other computers that can connect and share files properly on the home network.
