Inconsistent results from Windows Networking

I operate several different Windows computers and rely heavily on Windows Networking. In order to describe this problem I have 4 computers running on my own private network. Three of the four are connected to the network via Ethernet RJ45 Adapters. One is connected via WiFi. There is also a Network Attached Storage (NAS) device connected to the network.

The device names are as follows:

• Uranus Windows 11 Laptop
• Neptune Windows 10 Desktop
• Mars Windows 10 Desktop
• Venus Windows 7 Laptop
• MyCloud NAS

Using File Explorer the only computer that displays the expected view is Neptune. My intention is that all the computers are setup the same way. As far as I can tell that is true but given that this problem exists I must consider the possibility that some mistake/s exist. I made 3 screenshots that demonstrate the problem. A screenshot from Neptune follows:

Compare this to Mars which follows:

Compare them to Uranus which follows:

It does appear as though Mars & Uranus have the same deficiency but the one other computer that they detect are different.

It is also a little curious the the NAS named MyCloud only appears on Neptune when selecting Network is the File Explorer. However, the Y: drive that is assigned to it functions correctly on all the computers.

Hopefully, this is a somewhat simple problem known to those with the right kind of expertise. I've now spent an awful lot of time trying to find an answer.
