I have uninstalled Norton Antivirus manually and after I reboot the computer, my laptop cannot connect to the internet anymore and keep saying that it cannot renew the ip address. I have tried many things including uninstall and reinstall the network adapter and also tried to use winsock xpfix, but all don't help. All the connection is ok except the renewing of ip address. Can someone here is an expert on this? Please help.
