DNS problems

My cousin is living in an appartment sharing a wireless connection. She is having trouble connecting to major websites like google.com yahoo.com dslreports.com but can connect to sites like download.com and ocforums.com . Anyways I think she is having a DNS problem because she could connect to sites like google.com and yahoo.com if she used the IP's 66.94.230.34 and 216.239.39.99. I tried doing some work on her computer using netmeeting and I ran antivirus and spyware checks (adaware spybot) and other stuff and it all came up empty. Occasionally I could get google and yahoo to work for a while but if I cleared her cookies it would just stop working again. Anyone have any ideas on how to fix this, if you need more info I'll be happy to get it.

Put a known reliable DNS in her config.

If that doesn't help, run a packet sniffer and see what happens. Nobody seems to do that.

You don't sit around a broken computer looking at it, contemplating what could be wrong, instead of opening it up and fixing it, do you?

You have to look under the hood, otherwise its wild turkey chasing like most threads on here.

Can you think of any examples?

63.172.195.6 is a dns server I run that is pretty reliable.

Ok I fixed it, for some reason her primary DNS server wasn't working so I switched to her alternate and it works fine now.
