Do the windows instructions from Comcats require that you set some sort of host name? If so you will need to so the same in your /etc/dhclient.conf. We've also had reports of ISPs that will only issue one active lease for a given connection and thus if you don't release the connection on one machine, another won't be able to obtain a lease. If that doesn't work. You need to obtain a tcpdump, possiably run through the net/dhcpdump port to see what's happening. Any output from dhclient would also be useful. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
