Hi TheRafeSCV,
With Win 10 1809 build 17763.134, I have the problem not showing my computer, but only in the specific case when the PCs have both Ethernet and Wi-Fi adapters and the connection is done through the Ethernet. I gave the detailed description in another post,
but for some reason they don't let me put the link to the other post in here.

Clearly when it does not show my computer, it is also not visible from the other computers in the same network. Restarting the service "Function discovery resource publication" makes my computer visible again. Also it keeps showing after a normal shutdown/power
up if the power option for 'Fast Startup' is turned on, but my computer disappears again after a PC restart.
To recover I need to restart the service "Function discovery resource publication" again even if it is already running.
All my computers are on the same workgroup al running the same Win 10 1809 Build 17763.134, network discovery is enabled and my network adapters are set for private network.
Keep in mind that with Win 10 1803 everything works fine providing that "Function discovery resource publication" is set to start automatic, with 1803 there was a different bug and the service was not started at all unless it was changed to Automatic..
One more detail for 1809, if I disable the Ethernet adapter and connect to the router with the Wi-Fi adapter I don't have the problem, my computer keeps showing up after any PC restart.
If I re-enable the Ethernet adapter the bug returns after the PC restart.
Note that if I issue a Network reset my computer becomes visible after the first PC restart, but fails after that on every subsequent PC restart.
