The first step is to find out what exactly is wrong. Among the things 
you can do are:
- post your /etc/resolv.conf maybe there's an error in it
- do a
ping 217.72.195.42
(217.72.195.42 is what my DNS gave me as IP of www.web.de)
- do a
host www.web.de
- ping the IP of the nameserver
- do a
telnet <IP of the nameserver> domain
- if there's some other machine/device connected via IP in your local 
net, ping it's IP
- post the output of
ifconfig
