Icons for Network Computers not Showing

[tigerdlg]

I have FreeCommander 917 64-bit installed on three computers. All three are on the same home network. On one, my main desktop, the icons for the other two computers or itself do not show under >Network, either on the tree or in the display. They both show up if I use Windows File Explorer. The drive mappings to these other two computers do show up under the main computer name, and those mappings work properly. I don't think it's a setting I have wrong because I exported the FC settings to a file and imported them on the other two computers, so the settings are the same on all three computers. Two other devices (my Arris router and my Roku) do show up under >Network as they are supposed to. Anyone know what might be causing this? Thanks for any help.
