Win 10 PC can't see itself under Network Folder

I have two PCs on a home LAN. But only one of the two appears under the Network Folder.

I remote support family computers. There are two computers PC-1 and PC-2 a LAN. Only PC-2 is listed under the Network Folder (of both PCs). But PC-1 is not listed under Network Folder of either PC. I can type \\PC-1\c$ from a remote computer and it connects just fine. So why won't PC-1 appear under the Network Folder of either of the two PCs?

PC Specs

• Both PC’s running Win10 Pro x64 v1909 Build 18363.1016
• PC-1 is a Dell Optiplex 755. PC-2 is a Dell Optiplex 990
• PC-1 has Intel 82566DM-2 Gigabit Ethernet Adapter w/Driver version 9.13.41.3

PC-1 Setup
