Thanks mate. Ah so open dns thing will block facebook too. He wants this site to be blocked for his kid, if it gets blocked for his wife too he will get killed lol. Anyways here's what we have tried today and need your help
1. We blocked few sites via K7 total security anti virus's parental control option. The websites were blocked in firefox but out of those sites facebook was accessible via chrome. We literally spent like an hour messing up with the settings and then we gave up. What could be the reason for this?
2. Is it possible to create a password(and not a different user) in win xp. I mean everyone will be able to access the same account(the admin one in a way) but if he/she wants to change the system settings, then the system will ask for the password? By this thing we can have a go with the C:\Windows\System32\drivers\etc\ method.

have your friend set up seperate regular account for his kid, and restrict access to to system folder. a regular account should not be able to access the etc folder without the password.

having said that, one can easily bypass any restriction by simply using TorBrowser. so your friend needs to talk to his kid about the dos and don'ts . having previlages revoked if he does something naughty. move the PC to living room, and access should be permited only in presence of adult. these are the steps needed to ensure a kid doesn't access those sites. but still he can use those sites at a friends place.. so you cant have any control on that.
