Question : Trouble accessing internet.

Have a small network with all clients running windows xp.  For some reason I can't access the internet from  one of the clients.  Others are working fine.  Network consists of wired ethernet, behind a netgear firewall/router connected to a cable modem.  Netgear router functions as DHCP server.  ipconfig returns same information on each client (i.e. defualt gateway, DHCP Server, DNS server all point to IP of router).

On problem machine:

Can ping internally with IP address, ping routers internal and external ip, can ping external ip - but can't ping using host name (i.e. can ping 72.14.207.99 but not www.google.com).

nslookup will resolve with either IP or host name

I have reset all the hardware, used ipconfig (release, renew, flushdns), disabled/enabled NIC.

Not sure what to try next any suggestions would be appreciated.

Answer : Trouble accessing internet.

NST (http://networksecuritytoolkit.org) is based on Fedora, but is one I've used before. Nice GUI.
The thing is, if you can resolve domain names with a live CD it's just one more confirmation that something in windows is screwed up. :-|
I think we're all rapidly moving towards that assessment, anyway.

Back on the 'cover the basics' front, you swapped ports on the router with another machine to ensure the problem didn't move?
Then you swapped NIC-card-end of the cables with another computer to eliminate the cable from the equation?

Did you try uninstalling the NIC from Device Manager then reinstalling it using the latest drivers?
Besides fixing any possible problems with driver corruption (or mixing, if it's been upgraded numerous times), that should redo all the bindings, too.
