    Using ICS:
    Code:
    modem==[B]Primary[/B] computer===router---other PCs
    the firewall on the Primary will control access of other devices, but it's a pain to configure AND the Primary must be running for anything else to have Internet Service (including even simple email).

    the more typical layout
    Code:
    modem===router --- All devices
    is far more practical but only the common router is available for access controls and
    with the average home-router, it is limited in the number of keywords or urls that can be managed.

    Each PC could have its own system32\drivers\etc\hosts file and block access with
    a line per site (meaning everything at a given domain) like
    Code:
    127.0.0.1  blocked_domain_name
    but then you need to update all PCs with every change and recycle the DNS on each machine using
    ipconfig /flushdns
    net stop "dns client"
    net start "dns client"​
    while effective, this technique is all-or-nothing, ie all users are denied uniformily

    what i found

    Ok so its imblock and all i want to do is to run it from the server so all the computers on the network wiil be able to use it.

    And i already installed it but i have to manually put it on all the pcs in one of the room, so is there anyway to put it on all the pcs at once.

    you've arrived that interesting problem of how to administor
    (or configure and control) mutiple systems from one place (aka, the administrator's system).

    big companies do this with the Domain Controller (DC) software which is expensive and a whole new set of programs to learn - -
    not very practical for the home user.

    without a DC, there are really just two kinds of choices:
    a) use something in the network above all these systems to control what they all get to see or access

    b) install some program EVEYWHERE, configure it on one system, and then find some means to copy the configuration settings to all of them.

    when we typically have home networks like
    Code:
    modem==router---> lan attached PCs
    One central location that shouts at us as a candidate for centralize control is - - - the ROUTER.

    If you can pick a good one and get sufficent control there, then your task is not too difficult.
    My NetGet router allows Key Word Filtering and will block any URL which contains any
    word or work fragment in the list of keywords. Sadly, this is limited to a small set of key words and
    will never catch everything (ie: too many ways to create URLs which do not imply the content on the page).
