    Hi all,

    Over the past couple of years I've used Kerio v2.1.4 (driver version 3.0.0)
    with no problems. I have win98SE. Over the past couple of months I have had
    problems connecting to the internet. I have cable broadband. The problem is
    often solved by simply turning the modem off at the powerpoint and then
    turning it on again. A tech at my ISP suggested I change the CAD5 cable
    which I did...no improvement. I rang up again yesterday and reinstalled my
    network card driver (SMC1211TX) as the driver had reverted to a Microsoft
    driver...I now have the correct driver but the problem persists. The tech
    told me that he felt my Kerio firewall could be the problem..maybe a setting
    needed changing. However, I have not made any changes to it since
    installation..and frankly I don't fully understand the settings! Whilst on
    the phone to the ISP tech I noticed that the IP address had changed to
    something like 169. something instead of 210.something...clicking "release
    all" and then "renew all" fixed it (but only after a reboot), and today when
    I turned my computer on it had reverted back to the 169.something. I turned
    the computer off then on again and all is working again..with the correct IP
    number. So...my question: Could the problem be with Kerio? If so, could
    someone suggest what settings I should check? I know that my security level
    is set such that I get a prompt if I want to connect to a site etc. Sorry
    this is so longwinded! I have just deleted the persfw.conf, and rebooted to
    reset Kerio to default settings...I can then allow/disallow connections to
    various sites etc..maybe this will help?
    Cheers,
    Paul

    It doesn't sound like a problem with your firewall. Whenever your computer
    get's an IP address starting with 169.254.x.x, it's a default IP address of
    Windows when it can't get a real IP address. My guess is that you probably
    have a NIC that's going bad. Since you've already reinstalled the drivers
    and it didn't help I would tend to lean towards a bad NIC. I would try
    changing the NIC and see if that solves it.

    Hi Ray: Yes, the tech at my ISP also said that may be the case...I'll look
    around for another.

    i agree with Ray. It is most likely a NIC. However, perhaps further
    explanation of what Ray is saying could help you track down the problem.

    169.blablabla is a Microsoft internal address. It means that for some
    reason, your computer (specifally the NIC) cannot communite with your DHCP
    server (where you get your proper IP address). it is possible (however
    unlikely) that your firewall is blocking you from getting to your ISP's DHCP
    server. if the problem was the firewall, then why did turning the modem off
    resolve the problem?? doesnt make sense.

    anyway, my suggestion is to start switching things out so you can use a
    known good/known bad approach to this problem.

    1) begin by changing your Network Card
    2) disable the firewall (you may even have to uninstall it because
    sometimes fragments of firewalls stick around and active even when
    disabled). if you completely uninstall your firewall and the problems
    persist then you have eliminated the firewall as the problem
    3) try a different computer. if the problem persists at this step, I would
    think the problem is the modem not letting your computer communicate with
    DHCP from your ISP
    4) try a different modem

    good luck,
    Darren
