Can't ping dns name but can ping ip

I'm running Windows XP service pack 2. The problem I'm having is that I can't
connect to the Internet. When I bring up a command line, I run ipconfig and I
have an IP address and the IP address of the DNS server is correct. I then
ran nslookup to lookup the IP address for www.google.com and www.yahoo.com.
Both names successfully resolved into an IP address. I then used ping and I
was able to successfully ping those 2 IP addresses. But if I try to ping the
DNS names, the ping fails with a timeout error. I installed an anti-spyware
problem and an anti-virus program and made sure my system was clean. I used
netsh to reset the TCPIP protocol and I also tried re-installing TCP-IP from
the installation CD. But I'm still having the problem. Is there anything else
I can do other than reinstalling XP?

What is the underlying problem you are having that led you to try this test?
Are you unable to open www.google.com in a browser? If so, that isn't a DNS
problem...there may be something else going on.

You are correct, I'm having a problem opening a web site in a browser. If I
try to go to www.google.com (or any other web site) I get an error that IE
cannot display the webpage.

I fixed the problem. Seems that there was a failed SP3 update on the computer
and after uninstalling SP3, the networking stuff starting working correctly.
