DNS Problem?

I was going through my C drive performing a
little "housecleaning", and I believe that I deleted
something necessary for the cable internet to run. I
hooked up the modem to the other computer, and it works
fine. So I called Comcast, and the computer can ping a
valid IP but cannot ping a URL, so they said it is a DNS
issue. Any ideas on how I can resolve this?
