Issues networking two Windows 10 computers on a home network

Question

Here's my issue:

I have two Windows 10 machines. For simplicity We'll call them "Machine A" and "Machine B".

I'm on "Machine A". If I go into the file manager, and click on "Network", I can see both "Machine A" and "Machine B".

However, when I go onto "Machine B", and look in the same "Network" location, I can only see "Machine B".

We've had this problem for a few months. I don't know if this is a Microsoft Update thing. I believe the computers are set up close to identically. One is mine, one is my wife's.

We're running Norton 360 on both of them as well.

I noticed this problem when I tried to share out a drive I have. My wife tried to access it and could not do so.

I've tried several different things to make settings identical. I think I'm probably missing something small, but I don't know what.

Anybody have any suggestions as to what I can try further?

First, not sure why the question was downvoted, but whatever.

I figured out the answer. On one machine, I had a setting set to "public" that should have been set to private.
