i have an xp pro system on a network with 2 other xp machines. connected through a hub to a cable modem. all 3 were connecting to the internet. recently 1 machine stopped connecting to the net. nothing i know of has changed internally. changing the nic didn't repair it. changing cables and ports on the hub also didn't help. reseting tcpip didn't help either. the net connection says it's connected. gives a 169.xx ip addy says the nic is working fine. setting are for getting ip addy auto, use dhcp. auto detect settings. the other 2 machines have no problem connecting to the net. i've tried connecting without the hub (connected straight to the cable modem) and with the hub but with the other machines turned off/on. nothing changes. when i try using ipconfig /release it says no adapters available to preform this operation. same for /renew. any suggestions? if you need more info leave a message. it's really pushed me to the end on this problem. thanks everyone
