I have a local network with my machines. One is a Vista laptop, one is a W10 laptop and one is a W10 Desktop.
The W10 Desktop is my ‘main’ machine and it can send or fetch data from each of the other machines. The W10 Laptop can also send and fetch data from each of the machines.
The Vista Laptop can send and fetch data from the W10 Laptop but NOT the W10 Desktop.
The following first image is from the Vista laptop. The subsequent images are of the sharing configuration of the W10 Desktop
