Win11, Net View Problem on LAN, W10 and W11 differences

I have 'Googled' for the Error 53, and tried every possible suggestion/correction. All I could find and what they pointed to are CORRECT?

I have replaced the Router, and I think it was working before.

2 basic problems, both W11 Home and W10 Pro when the CMD line NET VIEW is used get and Error 53. However, on W10, Windows Explorer sees both PC's but on W11, only the other one, the W11 PC does not show?

What the W11 PC sees:



The above shows the error and my other PC in Windows Explorer, and I can TRANSFER files to it.

Now what the W10 PC (Wife's) see:



I should note that using in NET VIEW either \\sharename or \\IP Address format works?

On the W11 PC (IRVXPS8940) looking at Wife's PC:

I'm wondering is the MACHINEKEYS is involved? Don't recall seeing that before.

Any ideas? Again, all the standard checks, File Sharing, Private settings, Services, etc. have been checked?
