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.
