Most likely it means that your dns server is down and you'll have to use another dns server, temporarily, for name resolution. If you are on a LAN managed by an administator then there's probably a dns server on your network somewhere, but if you are at home, it will be a little easier to fix.
When you type an address into your browser, such as www. google.com, that name must be resolved to its IP address, so your computer can find google. The browser doesn't understand only the names you type, they have to be matched up with their respective ip address and that's what the dns server does. If the web site you're looking for is not currently in your computer's DNS cache, and it is not in the "hosts" file, it will have to use the dns server, that is, if you want to get to the web site by typing the name. You can get to the website if you type the ip address into the browser, but knowbody like to memorize hundreds of those, that's why there's dns. If you open a command prompt and type: ping
www.WEBSITENAME.com, it will respond back with the ip address of that website... You can then enter that ip address into your browser if you need to get to the web site, right away..
If you want to resolve the issue immediately, you'll have to find another dns server in your area. Google "dns servers" and add to it the city you're located in.
When you have found some dns servers in your area, post back and I'll tell you what to do next.. Or, you could just wait a little while and the dns server may just come back up...
On the otherhand, in some cases, the dsn server is the router/gateway of the computer you're using. Your problem may indicate a problem with your gateway/router..
