I have two computers connected to a Linksys Etherfast Hub and my DSL modem attatched to that and both computers keep assigning themselves the same IP address from DHCP. Then they both display the "There is an IP address conflict with another computer on the network." This is a problem, obivously, because neither can then connect to the internet or each other like that. Sometimes though, one will connect and the other wont get an IP address. I've done the whole release/renew and they either both get the same IP or one fails and the other is successful. When I connect just one computer to the hub or straight to the modem, it correctly gets IP/DNS and such and connects to the internet just fine. I bought a new Switch to replace the hub but it has the same problem. Which leads me to believe it is one or both computers that are the culprits. One is a computer I built a few years ago and the other is a week old Compaq. Both are running Windows XP Pro SP2. I have not manually assigned an IP address. Any ideas?
