Help fixing Network access restrictions

  1. Hello, I have a quandry
    For an unknown reason I have one machine on my home Windows XP network that behaves strangely when accessing the network.
    What does work is any URL that starts with https or ftp.
    Both Internet explorer and firefox time out when trying to access any site that starts with http.
    The machine cannot be accessed across the network by other machines or see the other machines on the network.
    The machine cannot even log into the Linksys router.
    This machine is hardwared to the router.

    I'm typing this on my laptop which works fine on the same network. I've pulled the network cable and attached it to this laptop and there are no problems.

    I've turned off the firewall and deinstalled my VPN software and antivirus software. I've poked around at various settings but haven't seen anything I recognize as a problem.

    Any ideas?

    thanks
    jim

    Start be checking these settings in the browser:

    Control Panel> Internet Options> Advanced tab> HTTP section> check both lines> Apply> OK.

    Turn the AV program back on ASAP.

    VPN issues

    get the FW running (at least the default MS version).

    Many people do not understand the impact of a VPN.
    You have a real problem if the VPN is not connected AND you can not browse http://www.google.com/
    If the VPN is connected, all browser requests from your browser are now routed
    to the remote VPN system and the results are dependent upon how that system
    is configured. Frequently such systems are intended to access business applications.

    The remote site to which you are connecting using the VPN would be exposed for
    infections if your LAN systems were accessible at the same time you were connected.

    VPN venders know this and intentionally configure the routing so as to disable LAN access -- this is all normal behaviour.

    Can it be leftover's from the VPN?

    Thanks. Don't worry, I turned the AV and FW back on.

    I'm familiar with the VPN and the problem with tunneling. That's why I disconnected and deinstalled the VPN software for now. It had been running without a problem.

    "You have a real problem if the VPN is not connected AND you can not browse"

    This is the problem. Without the VPN I'm still stuck. I wonder if there is some reminant causing trouble.
