Lan mode can see all my PC content

[Rocksteady]

Hey all,

I just joined this community in the hope someone can shed some light on my 'issue'. It is not really a problem, but I do wonder how safe my system is tbh.

The thing is that I have a cpl of droves and folders shared on my system, so I can watch movies and listen to music on my AC Ryan. However, when I enter LAN mode with BS player on my Galaxy SII, it can see ALL content on my computer. When I search my network from any other PC, it only shows my shared folders, which obviously is the way I want it to be. Do any of you experts know if this is normal, or what I could have done wrong with my security settings? BS player can even see my entire C drive, which does bother me a bit, after all, maybe my security is compromised or BS player has a way of seeing things.

Any help or insight would be greatly appreciated, thanks in advance.
