GoDaddy support: Domain mapping

Yesterday I registered two new domains, and instead of going through EasyDNS, which charges $35 per year for registration and DNS, I went to GoDaddy, and got it for $9.

But apparently, unless you're also hosting with GoDaddy, that does not include DNS. I've hunted all over the site looking for a way to map domains to an IP address, and while they will "forward" the doman (not what I want) they won't map it. I then called their tech support line, was told the wait would be two minutes, and hung up after fifteen (and the ads, these guys are always pushing stuff at you).

So my first question is -- is there a way to get GoDaddy to map a domain? How?

Second question -- I've got four Windows 2000 servers and one Windows Server 2003. Do they have a domain name server built in? I think they must. Somewhere. Where? How? Arrrgh, I didn't really want to learn how to do this.

PS: The domains are independentpodcasters.com and indiepodcasters.com. Yeah, isn't it a shame that a medium that was supposed to be all-indie-all-the-time will probably need to distinguish between people who sign with MSM and those who do it for love.
