Specs: Windows 2003 , NA
I have two internal DNS servers running Windows 2003 that are configured for "active directory-integrated". My internal domain name is the same as our external domain name (I didn't set it up this way). Our website ( is hosted by a third party provider. I have configured a Host record on my internal DNS servers that point all requests for to the IP address of my website provider. This setup works fine, except when someone tries to access our website using only (omitting the "www"). When a user tries to access our external website using the said method the result is "page cannot be displayed", which is to be expected since our DNS servers are considered athoritative for the domain. I need to be able to access our externally hosted webiste by using the internal domain name (i.e., without including "www". I have read up about split-dns; however, I don't think this is really what I need, since I am not hosting any webservers internally that users need to access.

My question is, how do I create the abililty to access our externally hosted website by using only the domain name, (without the "www"), when our local domain name is the same as our external domain name?

This is why you NEVER use Root DNS (i.e. .com, .gov, .net ...) for your internal domain. I think that even if you get the lookup zones to recognize as being an external address this will cause your internal routing to fail because it will try to run to that domain instead of yours and will mess up your local domain.

The question is are people out side of your domain (the web users) able to access your page without the WWW is is it just your internal users?

If so then you may just want to enter a HOST A record using a derivation of the external domain like which points to your ISP or tell people not to forget the WWW or a more expensive solution might be to setup a Proxy Server which will cache your site for your Intranet.

Yes, only internal users within the local domain have an issue accessing our webiste; users accessing the website from outside of the local domain (internet) do not have any problems when accessing the website when omitting the "www". The website is hosted outside of our local domain by a third party. I have read that DNS delagation may work for this issue; what do you think?
