Edit resolv.conf and change "192.168.0.1" to the IP address of your primary DNS server. 
If you don't know how to get the IP address of your primary DNS server, read the tip below.

Tip: To find out the IP address of your primary DNS server, connect to internet (If not online) and do the following:
On Windows 95/98/ME: Open Start Menu, choose Run, type in "winipcfg", click on More Info >> and use IP address listed next to DNS Servers
On Windows NT/2000/XP: Open Start Menu, go to Accessories, choose Command Prompt, type "ipconfig /all" and use the first IP address listed next to DNS Servers

Tip: If you use a DNS forwarder like Winroute or Wingate, use it's IP address in resolv.conf instead
