Dns server error on wireless netbook running windows 7 starter?

My acer aspire one netbook was working fine as of last night. I turned it on this morning and I am getting a dns error for certain sites. I have an internet connection through wireless. I can sign into all my messengers, access google, facebook. Most other sites are showing a DNS error. I am running windows 7 starter. I have already reset the router and did not help. I also tried switching the protocol v4 dns settings to those recommended and this did not work either. Any help is greatly appreciated.
