One computer is not visible from the others in the network icon

Hi,

Verify the state of the following services on the "missing" computer.

- Function Discovery Provider Host
- Function Discovery Resource Publication
- SSDP Discovery
- UPnP Device Host

I have that problem with one particular machine and have not been able to determine why it loses visibility.

When it disappears running this command from an elevated command prompt and rebooting always restores it, until it goes missing again. The command is "netcfg -d". It is completely safe and resets the network connections, all of which are restored at boot up without the need for user interaction.

I have already tried that. It was step 2 of the page I had linked in my OP.

I tried the netcfg -d command and rebooted. Unfortunately, it did not fix my problem.

I think my issue is a different one than yours, though. It is systematic. There is no time that it ever shows up in the "Network" icon, not locally or from any other machine.

BTW, I tried temporarily disabling the Defender firewall, and that also didn't fix the issue.

I have too refrained to install SMB1 and I have very slow / incomplete Network discovery outside my domain. I try to use Mappings and direct link as much as possible. Although It does not seems to affect multimedia sharing servers / client, But sometimes I see only the Domain computers and other I can also see the different workgroups and their computers on the network.

My domain Master browser is on the DC. And I never understood what was up with that. I can see frequent MB election refused on my DC. but that should make client use my MB instead and make machines viewable on the network. but it does not always works.

FYI, there is no domain controller on my network. Two of the computers are in the same room, on the same network switch. I haven't setup any workgroup.

Well, all computers need to be in the same Workgroup,, and have NetBios over TCP enabled. Besides that you have pretty much covered it.

How To Fix Computer Not Showing Up On Network Issue

I'll take a look, but I think I left the workgroup as the default.

Even if they aren't all on the same one, I don't see why the system doesn't at least see itself in the network folder when logged in locally.

Check out the link I posted, you may find something you haven't tried yet.

I just did. I tried everything except the SMB 1.0 for security reasons. Nothing worked, unfortunately.
