Cannot Restrict Access On Lan To My 2 Pc's Only

Starman202

Hope someone can help me. In our neighborhood we have about 10 residents on a LAN/WAN??? controlled by 1 resident. For connection I have a LAN modem which connects wirelessly to an aerial at resident 1. I have 2 computers running off the LAN Modem to a hub with one PC with Win 7 Ultimate 32 bit connected and the another one with XP SP3. Thinking incorrectly that I was setting up a home network, (which does not work between Win 7 & XP) in trying to get my 2 PC's to talk to one another I have permissions set on all drives of both machines setup for "everyone".. However I have discovered that now all 10 residents can see my 2 PC's. While I can see both PC's from either machine, (apparently via the LAN) in trying to change the permissions in Windows 7 & XP from "Everyone" to restrict access to the names of each of the 2 pcs only, I can only see "users and Administrator" on that particular machine only and cannot add a user/name of the other PC.

How can I stop the other residents from seeing my machine but allow me to see either of my machines from one another? I would naturally need to connect to the resident 1 for access to the internet but would not want him to have access to my files. Can this be done via BitdDefender Internet Security 2011?
