WWW/DNS issues

I must be having a brain fart because i feel like a moron!

We have a network setup with 36 Windows XP Pro machines that login to a single Windows 2003 Server (standard). The server is doming DNS, DHCP and WINS as well as some basic file sharing and is running Symantec Endpoint Protection (wich installed IIS).

Here is the problem - we have a new domain (lotusbakersfield.com) that is hosted by GoDaddy. We have their basic/free 5 page website. Obviously i want to be able to go to www.lotusbakersfield.com and it bring up the website. Well, from outside the network (IE from home, across the street, etc) the site resolves correctly and the website comes up. From inside the network, when I try to go to www.lotusbakersfield.com it gives me the Live Search page bringing me up all of the things with LotusBakersfield in it. If I go to lotusbakersfield.com (no www) I get the IIS help page that tells me that my site is under construction.

I would like to be able to get to the GoDaddy hosted site instead of the internal IIS site... Can someone please help nudge me in the right direction?

Thanks!
Tim
