DNS settings in WinXP Pro

I have telia broadband, and normally setting it up in Win98 is no problem as I have a little manual guiding me through it.

I recently upgraded (?) my other PC to XP pro and now I can't wind where the settings are stored.

it says:
open networks thingy (done)
properties (done)
DNS-configuration (done)
then it gives me a screenie (98 style) where they have chosen activate DNS
host : FOO
domain: telia.com
and all the DNS server lists are blank.

I can find the lists, but not where to type in the host or domain, someone please help.

What is your set up like...Do you access through a router...

not entirely sure, it's a little black box with light on it, hehe.

I think I'll call the customer help line instead.
