Machine Partly Visible on Network

[Cheemag]

[Windows 10 Pro both. Machine called BB has v 1909. machine AA has v 2004].

 

Need help with network.

 

BB has no problems.

 

AA will fail to show itself on the network, although it can see the other machine, the Readyshare drives and the TV.

 

At BB command prompt, doing dir \\aa\temp will give a directory, but AA is not showing in File Explorer or Total Commander.

 

A restart and a reboot failed to fix the matter (just after KB4566782). Then shutdown and start failed to fix it. Switching off and on again all

the network discovery/file/printer-sharing/passwording etc settings followed by a shutdown and a start finally got it to boot onto the

network.

 

So what am I doing incorrectly or what have I neglected to set up ?

 

Regards
