I'm guessing you meant to type DNS error. Have a read through the below and it might help. Particularly the action of attempting to repair your network by right clicking on your network icon as you can boot a troubleshooter there.
DNS stands for Domain Name Service. Most DNS errors usually indicate lack of a connection to the internet. DNS is used to translate human addresses (for example,
www.bhcblog.com) into computer addresses (like 10.64.254.11) ..
When you hit a dns error it usually means your computer cant get to the internet. If it only has the problem for certain addresses it means that either there's no entry for it or perhaps you mistyped it.
A couple ways to fix this problem :
1. Try right clicking on the networking icon in the taskbar and hitting repair.
2. goto a command prompt (start --> run, type cmd ) and type : ipconfig /release then ipconfig /renew.
3. if you goto control panel and then network properties and you go into the IPv4 settings for your network adapter, you can statically set the DNS. I recommend using a verizon DNS server 4.2.2.3 because it's easy to remember.
4. If none of the above fix it, try a different machine, it most likely means your internet connection may not be up properly. Check cables and connectivity and make sure you are getting an IP address.. If you goto the command prompt (see step 2) and type IP config you should have an ipaddress. If the address begins with 169.254 it means you are not being assigned an IP address and you will not be able to connect until you get one.
