I have a private home LAN with three Windows 10 PCs that are sharing files & folders among themselves with no problem - I just click their PC name under Network in File Explorer. Problem is, I just set up a new Win 10 PC but when I click on that new PC's name under Network in File Explorer on any of the existing three PCs I get an error msg saying I don't have permission to access the new PC.

I made the new PC discoverable and not pwd-protected, just like the other three. I set up the Documents folder in the new PC to be shared by Everyone with Full permissions. All four PCs are running Win 10 (ver. 2004). All are wired Ethernet desktop PCs except one existing PC is a Wi-Fi laptop.

This situation is weird because everything works fine when I go to the Search box (next to the Start icon) on any of the other PCs and type \\NewPC\Users\UName\Documents\. The same good result occurs when I set up a shortcut targeting \\NewPC\Users\UName\Documents\.

There is no hardware/connectivity problem because the new PC is seen by all the others and I can access the shared Documents folder\files in either of the two ways just described above.

Am I missing a setting, or something else? Thanks for any help.

Whenever I restart my pc, it does not want to connect to the internet, it appears connected but does not open internet pages, and the error solver says, it fails in the router dns, but it is not that, because in other devices it works fine, I must restart the internet modem or take out the ethernet cable until the line comes back, my service provider came and checked with his laptop, it works fine, they told me there is a problem on my pc. To connect the ethernet cable I use a HUB (photos) because my laptop does not have a direct connection to ethernet, and for some time, when I installed AUSLOGICS BOOTSPEED, I did some programming and it gave me an error in the device driver desktop, I don't know if that is doing something on my pc, I don't like to be connecting and disconnecting the ethernet cable, because it is supposed to work, no need to reboot or remove the cable. Since I installed AUSLOGICS BOOTSPEED, I HAVE GOT SEVERAL BUGS IN MY PC, I DON'T KNOW IF THEY CAN HELP ME TO SOLVE IT. I already tried everything.
