DNS settings for non-www address

This only occurs from inside our work network: I am unable to connect to our website, which is hosted on a totally separate network, when I leave off the www. to our domain name. Anywhere, outside of our network, it can be accessed by domain name or www.domain name. So, somehow my internal DNS isn't configured for this- but, another problem is that we go through our department's network downtown where our secondary DNS servers are, and they won't let me access the non-www domain name either. When I have my nic set to our DNS server as the primary, I get a 403 - Forbidden: Access is denied (no permission) error. And, when I use the downtown DNS servers, I just get Internet Explorer cannot display webpage or Firefox: Server not found. Our internal DNS Server is setup on Microsoft Server 2003. Your help is greatly appreciated. Thank you, Greg

Thank you, very much, n2fc! The problem is that my internal and external dns domain names are the same. This has been driving me nuts. Thanks again and for such a quick response, too.
