Check your ipconfig and verify that you have settings from the isp, gateway, ip add, etc...

ipconfig /release /renew if necesary

Ping yourself, loopback, default gateway, and DNS using IP address, (xxx.xxx.xxx.xxx)

You should recieve replies. Now ping www.google.com

The name will be resolved by the DNS, but lo and behold, your computer doesn't care.

Your Winsocks has been corrupted by spyware, and/or Norton when it tried to take care of the spyware.

If you have Windows 95-98se you must reinstall the TCP/IP stack, and if you have Windows2000 or XP you simply cannot reinstall the protocol. I found a tool that does this for you, and WILL fix the Winsocks via the registry in 2000 and XP, NO NEED TO RELOAD OS!!!!!!!

Microsoft will tell you there is a DNS error, but they are wrong, running Ethereal will show you that the DNS resolves the name correctly.

If you haven't already reloaded the O/S, google for an app named Winsockxpfix. Run it, MAKE SURE you back-up the reg (doesn't really matter if u were gonna reload anyway) and it WILL reboot WITHOUT warning! It is necessary to reboot, so beware.

It seems this also clears up the Client Common thing, and a a possible ending explorer now on shutdown.
