Re: xp WON'T auto renew IP address after lease

Yes, XP should get the new address automatically. However, if your ISP is
playing games with variable lease durations and cycling IPs out of the
available range; then when a DHCP client already has an IP and attempts to
renew it, it is likely to receive a NACK response. This results in a longer
broadcast conversation between the client and the server and increases the
chance of collisions, lost/dropped packets, etc. If you periodically
release and renew, you 'should' be able to avoid lease expiration. This is
more a case of your ISP maximizing the chances of lease negotiation failure
than a 'Windows' problem. The DHCP process is defined and governed by
various RFCs; it is not controlled by Microsoft or Windows.
