    Hi does anyone know if it's possible to block a website from being accessed on a computer without being able to undo that command

    You blocking it from yourself or someone else. I'm sure the someone else would not know how to unblock it if you were the one to block it.
    Youtube it, always a way

    There are always ways around it even if your ISP were to block it. Just look at the recent attempts in Turkey to block Twitter as an example.

    Not possible. Even if you could irreversibly block it at operating system level, the user could use a LiveCD, so they wouldn't even be booting into the OS. Block it at router level, they can use a proxy.

    Then block proxies.

    Which ones? Hell, setting up your own proxy is pretty trivial if you have any kind of technical ability

    Depends on how much you control that computer and/or the router they use to access the web. Also how technical they are.

    Are you looking for some form of parental control/filtering application?
    Or just filter one or two sites ?

    If someone was not technical, then you could alter their hosts file, typically residing in C:\Windows\System32\drivers\etc\hosts

    And add a line at the end.
    Eg. if you wanted to block www.boards.ie you'd add the line
    127.0.0.1 www.boards.ie

    Or if you control a home router, then depending on the make and model (you may have to post that here), there may be parental/content filtering available to you there.
