    If there is a way i could not find it, worked on the problem for about 8
    hours before i gave up on it. Not a huge problem, but curious
    none-the-less. The only thing i can think of is dhclient is not
    respondign the the dhcp server properly to finish teh transaction.
    Probably some wierd auth stuff, i dunno have not dug into it deep enouph
    to tell what the problem is exactly. And i prefer not too unless i
    absolutly need to, would have to figure out how. :)
