How do I fix my computer that has a DNS error?

I have recently lost the ability to connect to a web-site that I need for work. Also i lost my wireless connection to the main computer in the house. It to cannot get to the web-site. All the rest of the internet works perfect as far as I can see. I am running a line directly to the modem now with the same problems. I has turned off modem etc.. and still have the problem. I have been able to connect to the web-site on computers outside so I aa lost as what the problem is?

I get the DNS error and have looked on forums and cannot find what the problem may be. iT sounds like something simple as far as just something need to be reset?

I run windows 7

Thanks for the help

I assume you are getting the IP from DHCP (dynamic)
Did you fill in your own DNS servers or are you getting them from DHCP? If you don't use "open"
ones (I would recommend against that) you need to let DHCP set your DNS servers.

It is possible that your DHCP servers aren't serving up the ips.
From run/cmd

> nslookup www.yahoo.com THEIPADDRESSOFTHEISP

should return good values.
