Have you tried running ipconfig /renew on the XP machine? Have you checked the lease information in the DSL modem? A DHCP server will not hand out the same IP address twice. The only time I've seen something like this happen is when the DHCP lease times out for an IP and windows doesn't renew the lease on the IP, the IP is put into the free-ip's pool and handed out when the DHCP feels up to it... So if the XP machine is setup for DHCP, it got the IP via dhcp, it probably didn't renew the lease on the IP.
