Network Bridge on XP and other issues

    One of the PC's at home has developed a network issue. It cannot even
    connect to the local network. All other PC's can. I have 3 PC's, 1
    laptop and a linux server (e-smith) running.

    Firstly, I do not remember there being any "Network Bridge" in the
    network connections page but it has appeared with an IP address
    different to my local standard. It's IP address was 196.?.?.?. I
    overwrote it when trying to fix the network and can only remember the
    first part of the IP address.

    I have tried deleting the network bridge but the "Deleting Network
    Bridge" process runs for hours and does nothing. I left it for 10 hours
    overnight and no result.

    The hardware in the PC is NVIDIA. The Network Connections lists both
    LAN/ethernet and 1394 (Firewire?) network connections are available. The
    Ethernet is listed under the network bridge.

    This PC has MSSQL MSDE running on it as does my laptop. After I
    installed a firewall on my laptop I was alerted that SQLServer on the PC
    in question was trying to connect to my laptop. I blocked it and forgot
    to follow up on this.

    I ran Spybot last night with definitions 1 month out of date and it
    found nothing. Now I am unsure what my next step should be to sort out
    the network issue. I am sure it is involves deleting the Network Bridge
    and reconfiguring the ethernet TCP/IP settings but I cannot delete the
    network bridge.

    If necessary I do have some live CD's available (Knoppix, UBUNTU) that I
    can use to back up the necessary files and do some hacking of the
    windows files.

    All suggestions much appreciated.

    First, a couple of simple, standard suggestions (which you may have already
    tried):

    1. System Restore -- to get your system configuration back to a point when
    everything worked as it should.
    2. Disable (instead of trying to delete) the network bridge. Then run the
    network setup wizard.

    If none of this works, run "ipconfig /all" from a command prompt and see
    what you have -- and don't have.

    Did you originally use the Windows XP Network setup wizard to configure
    your connections? This wizard creates a network bridge by default, if
    you have multiple network adaptors. In your case you have two: etherenet
    and firewire. The 'Network Bridge' is used to provide connectivity
    between LAN segments or different network types e.g. LAN to firewire or USB.

    It *shouldn't* be causing the problem you describe as long as your
    primary ethernet connection is correctly configured and operating. If it
    is causing the problem, then the software is faulty.

    Have you tried starting from the basics:
    Check the parameters displayed in ipconfig /all on the bad machine are
    as they should be.
    Can you ping any of the other devices on the LAN?
