Computer not visible in network folder

Question

I have 4 computers running Win10 21H2 on my home LAN. I have network file sharing enabled on each computer.
All the computers can see each other's network shares, except for one machine that's doesn't show in the "Network" icon from anywhere, not even from itself when locally clicking on the "Network" icon. The other 3 computers have their own names in the network icon showing up. If I type \hostname , I can access the shares on the broken machine just fine. I would like to be able to use the mouse, though.

I have tried every method at FIX: Windows 10 Network Computers Not Showing in Explorer. (Solved) - wintips.org - Windows Tips & How-tos except enabling SMB 1.0/CIFS support, as I think it's a security issue. None of the 4 computers have this enabled, and 3 of them can see each other's shares just fine in the GUI.

I'm using a wired Ethernet connection on all the computers. The network profile is set to Private on each one.

I'm really stumped by this one, and the experts at tenforums have been also.

Could somebody from Microsoft please help with this ?

No, it doesn't work. The problem is still the same. The machine doesn't show up in the network folder, either locally, or from other systems.

Addressing it with \HOSTNAME works. I'm really puzzled by this.

Answer 3

On one computer, I'm able to fix the problem by uninstalling update KB5007186 . After the reboot, the computer shows up in its own network folder.

If I reinstall that update and reboot, the problem comes back. So, it seems there is a regression in that KB5007186 update.

Unfortunately, on another computer, the update cannot be uninstalled, so this is not an option to fix it.

Answer 4

I spent many hours playing with updates on all 4 of my Win10 computers, rolling many back, and then reinstalling all the latest ones. The 4 computers can now see each other, and can see themselves locally in the network folder. For how long, I just don't know, unfortunately.
