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: Open Start Menu, go to Accessories, choose Command Prompt, type "ipconfig /all" and use the first IP address listed next to DNS Servers
