I verified that, no conflict for IP address at all. I can see in DHCP
table, Ip addresses versus MAC addresses. Also my gateway (Router) is
192.168.0.1, my laptop is 192.168.0.2, my XP PC was 192.168.0.3, when
I boot by Win2K/Linux PC, either in Linux or Win2K, it is always
192.168.0.4. I plugged in new NIC card, then I configurte that, if I
plugin cabble in that then I got 192.168.0.5. All IP addresses are
unique as well as MAC's are Unique, but strange is, when I boot with
Win2K, all computers are out of Network (when my Win2K is booting, I
am running "ping www.yahoo.com" on all other computers, once Win2K
comesup, all pings says "request times out").

Thanks.
