My own PC in "network" sometimes does not show

The thing with which you're dealing is present since discovery of Microsoft, you're not a lone.

Network sharing simply does not work as expected.

Microsoft never bothered to fix home networking. Instead, they just assume you are on a Domain. They have abandoned the HomeGroup (read: HomeGoop) feature that was part of Windows 10 so now they tell us to use Network Locations (and/or simply map a Network Drive). If you want Network Neighborhood to get populated correctly in Explorer─which was called File Explorer before they decided to rename it and then everyone else except me kept ignoring the fact that they renamed it─it means you're on your own.

I have also suffered from this Windows problem that MS never seems to fix.
To fix it, when the machine would show up, I would map a network drive to the folder I would use. This became old so now, I just Pin that folder to the "Quick Access" area and I always have access to folders on that machine.

If you would be interested, I have written a pair of VBScripts that let me export/import the pinned folders area from Quick Access to a simple textfile. It works, but it still has a few minor limitations like not being able to import a pinned network folder when the folder is offline and hasn't been added to Network Locations─under This PC. Aside from the fact that it can tend to run a little bit slow for network folders, another minor limitation (that I should be able to fix if someone needs it) is that it assumes you haven't added both a parent folder and a subfolder that belongs to this same parent. Added them to your Network Locations, that is. Here are the scripts: QuickAccess.zip

interesting stuff here and also the insomnia app , how nice!

here something different happened yesterday evening..

So i thought, hang on a second maybe the hub is doing some funny business... so i unplugged the hub (which has a wired ethernet connection i am using now btw) and i simply put the PC on wireless without any ethernet for the time being.

restart.... voilà this same PC appeared immediately after restart (and also the second laptop), so i went ahh ahhhhh so it's the network...

then i put back the hub with the wired ethernet, disabled wireless restarted and now it works! total mystery - both have SMB disabled now and everything works fine... so, until next time....
