Hi, I have a local lan network that broadcasts internet and my local network. I shared it with a neighbor so he can use internet but I'm afraid that he could access my shared folders too. My systems are two windows 7 machines and one xp and I use WPA2-PSK and made my router not to reveal my network name (not to broadcast it's name) so how can I fix it? and how can I disable the $ hack? like if you know one of my machine's names, like computerA, you can access all it's drives, like for C and D you would write \\computerA\c$ or \\computerA\d$ ! tnx. p.s. I'm using workgroups, maybe renaming my workgroup name from default Workgroup? I'm bad at networking.
