Default nameserver

You need to enter the nameserver your ISP told you to use here. If you don't have it noted you can find it:

1. Open the Windows Control Panel (Start->Settings->Control Panel)
2. Open the Network dialog and select the Configuration tab
3. Select TCP/IP and click on Properties
4. Select DNS Configuration
5. The address you need is the top address in the DNS Server Search Order box

(That's for Windows 95 - it's similar for NT)

Only enter one address in the default nameserver box
