    In short it goes like this.

    Click Start->Run
    Type "dcomcnfg.exe"
    Turn it off

    Why would I write any more? It is nothing new and free to have already.

    Please see references above for the counter to this statement.

    As to charging for the knowledge. Yeah, it is my time and my mind that
    does the work, of course I am going to charge for it. Does UT provide an
    education for free to everyone?

    Hardly hypocritical, the information is free for the taking and the
    tools are readily available. Most of them already exist in the OS that
    was paid for. It simply requires that the time be put in to do it.

    To the open source easy to use statement, since windows is pay to use
    why would anyone expect to be able to manage it for free? I vote to
    spend my time making the free things easier to use so I do not have to
    buy windows.

    I live in the real world, it is harsh and brutal, it is in fact the same
    world we all live in. Unfortunately the universities are half the
    problem here. A fantasy world exists on every campus where the belief is
    that everything should be free and you should be able to do what ever
    you want. Only one catch, we charge to be here at university to have
    access to our fantasy world where you get this information and do what
    you want but we want you to give your information to us for free even if
    you are not in our fantasy world. That is hypocritical.

    Here we go again with this fantasy stuff, the information is free, the
    work to implement it is yours to do. I accuse nobody of doing a horrible
    job nor do I try to charge outrageous fees to make the accusation. I
    will charge a fair price for a fair days work. I simply have no sympathy
    when it is realised that a horrible job has been done. The real world
    works like that, it is harsh and brutal, we make mistakes and we recover.

    I think there is this thing called "Darwin's Theory of Evolution" that
    you can learn a lot about in university. It goes something like this.

    Life evolved through a natural process of random mutations and natural

    Sounds to me like we are living it in the real world whereby matter
    interacting with matter can create anything and that random mutations
    and natural selection will dictate the outcome. Those that have followed
    best practice will end up higher in the chain than those that did not. A
    direct result of this random mutation called a vulnerability that turned
    into a worm that made us realise that we have to evolve just a little
    bit more.

    Some select quotes from any dictionary. They seem to apply to IDS in
    this case.

    protect: To keep from being damaged, attacked, stolen, or injured; guard.

    guard: To protect from harm by or as if by watching over.
            To supervise entry or exit through; keep watch at.

    I appreciate the offer to join you but I think I may be busy with my own

    Full-Disclosure - We believe in it.
