so on my laptop when on my own network i can see my desktop pc and connect to the printer and shared folders, and vice versa, but say if i connect to another network, eg my neighbours, random peoples, etc and i go to "view workgroup computers" it will usually show the workgroup name then say its not accessable. everything works fine on my mums network aswell so i dont see why it works fine on 2 networks just no other ones. any ideas?
