Make sure Xp's built in firewall for that NIC is not enabled. If it is not, have you replaced the NIC? Checked the cable? Ya know, the basics? KTTD God Bless Our Soldiers

Your answer is so short and confusing.But thanks for your response. What's NIC?Net card? I have installed two net cards for a month.Now I have removed the 2nd card. I have also turned off the Firewall.What do you mean by "xp's Built in firewall"?My firewall is Zonealarm Pro. I can access the internet.Why check the cable? Any other response or advice?
