Visual InterDev Wiz and Alt port settings

Ok, so I'm going slightly insane here. I'm trying to import our company's internal web page into Visual InterDev on my computer. You wouldn't think this would be too difficult, right? Well, the problem is that since it is our Intranet they were able to use a port other than port 80 for http. Well, when I try to use the Create a New Web Project Wizard it says it can't find my web server. I think this is because its looking on port 80, which is disabled. Perhaps I'm wrong. Any thoughts? If you do think that the problem is the disabled port 80, do you know of a way to tell the wizard which port it *should* look at to communicate? Thank you in advance for your help.
