Vista Ultimate SP1 looses network connection

    At least once a day my I notice all my network applications like Skype, GTalk
    etc are trying to login again and I can't reach the internet with IE. When I
    look at Network Sharing Center instead of the usual Home (private) network I
    now have that and another Unknown Network, or only the Unknown Network shown.
    If I reboot I get just the Home network showing and everything works again.
    Sometimes I can disable the local area network adapter and re-enable it and
    the connection stays up for a while. Other times trying to disable lan
    adapter gives perpetual hourglass. Can anyone shed some light on this? I was
    hoping not to have to reboot so often.

    Dell XPS420 E8500 3.16Ghz
    Vista Ultimate SP1
    3GB DDR2, 500GB SATA, Intel 82566DCV-2 Gigabit NIC

    Just wondering but does your system go into Sleep mode when you leave
    it? I have this problem with four of the dells running Vista Business
    and all we ( the dell techs and I) came up with was to go into power
    management and turn off sleep.

    Yes, it happens when Vista comes out of sleep mode. As far as I can make out
    a second network is created "Unknonw Network" which has IP 0.0.0.0 Also the
    default gateway appears to have been changed to 0.0.0.0. I sometimes can
    disable and enable the network adapter and it reconnects, other times I have
    to reboot.

    I'm going to try using static IP instead of DCHP and see fit that cures it.
    Not a good fix on a LAN but I'm working out of a home office.

    Here's my config.sys taken when my system has been disconnected:
