To Dns Or Not To Dns, That Is The Question

[DoG]

OK, i have Windows 2003 Enterprise Edition running on my computer. I want to run a website from it.

My computer connects to the internet through my router, my router has an ip of 192.168.1.1 and my computers Ip is 192.168.1.2.

I have forwarded all ports from the router to the computer.

I have DeEns running with a dyndns domain (reborndog.ath.cx)

I have IIS installed, when it type my local IP into internet explorer i get the "under construction" page as you would expect.

When i try to connect via my domain name however i get "Cannot find server or DNS Error", that also happens if i type my ip address in there.

How do i set up windows 2003 as a dns server to allow the internet to access my site?

Thanks
