It seems I've been dealing with Windows share issues for years across multiple versions of Windows. It never seems to get simpler. 
I have two Windows 10 Pro systems (Brawn, Ardor). Brawn has been running for several years; Ardor is a new system brought up a couple days ago. I like having a single share on each computer in my home for exchanging files. I successfully created a share on Ardor which is visible and accessible from Brawn. I have been unable to do this with a share on Brawn and access it from Ardor. (Yes, I know I could use a single share on either to facilitate exchanging files but this just bugs me and it should work

- Both are logged into the same Microsoft Account.
- Both systems are in the same Workgroup.
- Both are on the same physical network, same subnet (192.168.0.x), and both can ping each other by name. The network has a router and two APs. Brawn is cabled to an AP. Ardor is WiFi connected to an AP.
- When I attempt to access the Brawn share from Ardor, it fails and clicking on [Network Diagnostics] it reports "file and print sharing resource (BRAWN) is online but isn't responding to connection attempts" -- see screenshot.
- Comparing the Network Profiles, I noticed that Brawn says it is connected to a public network -- it is not -- while Ardor says it is connected to a private network. I know a mismatch here can cause problems like this. So, I tried changing this via Set-NetConnectionProfile. The change was accepted and it did cause the Network Profile to show "Private (current profile)" which it wasn't before, but: 1) it did not fix the issue with accessing the share, and 2) the change does not last through a restart.
- I reviewed and compared the list of services on each (thinking maybe I'd disabled some pertinent service on Brawn) but did not see any significant differences I thought might account for this issue.
