How get subdirectory to act like root

I have installed DNN3 into a subdirectory on our site, per the recommendations in the FAQs.

But my problem is that the URL reflected in the browser is http://www.discountASP... and not the company domain.

I have searched this forum and the web and found suggestions for redirect, frameset, server.transfer, and tried all of them. Unfortunately, nothing is working as needed.

Is there a way to configure a site on DiscountASP that allows me to follow the recommendation of putting the DNN3 site in a subdirectory while preserving my domain name credentials and display in the browser?

I've posed it to support multiple times, and in the end I am told that this forum is the proper place to get the answer to this question.

Many, many thanks for anyone's help.

 

When I originally signed up with DiscountASP, I purchased a domain that I intended to use temporarily. After the site was set up, I asked if I could point a different domain at the site, and support was helpful and did this. Right now, the domain that points to the site is include.com.Name servers arehosted thorough GoDaddy currently, and are enabled.
