I'm so lost.

Let's get started:

I am hosted with Appliedi.net. I am using their reseller program. They support DNN v3 and v4. Under my account I installed DNN v4 successfully. If you go to http://www.technokelvin.net/DotNetNukev4/ you can see it. My first question is:

1)      How do I get to just show www.technokelvin.net, without the /DotNetNukev4? I know it’s because in the wwwroot I installed DNN in a folder called DotNetNukev4, but in order to get rid of that section in the URL do I have to install it in wwwroot without putting it in a folder? Having it scattered everywhere?

Here comes the complication. Under the same account (For my host appliedi account that is, not DNN) is a 2^nd domain name, www.djcheeks.com (That is a client of mines domain, and just the domain. He has no website up at the moment). Now I know DNN allows you to have multiple portals with multiple domains so I created a 2^nd portal with the portal alias www.djcheeks.com but going to that site (You can try it for yourself) brings up this:

Directory Listing Denied

This Virtual Directory does not allow contents to be listed.

Which I understand because with my web host if you don’t have a web site and try to go to a domain it shows that. That’s the problem. Going to www.djcheeks.com still takes you to Appliedi’s website, not the portal I created with DNN yet somehow www.technokelvin.net/dotnetnukev4 will bring you to the portal. I looked everywhere in my DNN admin and host options to find a URL for www.djcheeks.com (Because by default when I installed DNN and created my technokelvin.net portal it created a default portal alias technokelvin.net/dotnetnukev4 that cannot be edited, djcheeks only has one portal alias and it is editable) but could not find it. 

DNS mapping (I’m guessing) occurred during installation. That’s why technokelvin.net/dotnetnukev4 works. If under that same account with my web host I have a 2^nd domain does that DNS need to be mapped to DNN as well? I thought the DNS for both domains were the same? Under name servers for both accounts they are the same as well as the IP address tied to them.

Do I need to wait for a DNS to propagate from my web host to DNN and that’s why www.djcheeks.com still takes you to my web host and not DNN?

Do I need to tell my web host to get off their asses and change a setting in IIS to make my domain point to DNN like they did with technokelvin.net/dotnetnukev4?

This helped me get a better picture but the video tutorials cost money so I got left in the dust:

DotNetNuke Multiple Portal Method

DotNetNuke allows you to use a single hosting account for multiple domain names. Within DotNetNuke, you simply create a portal for each of the domain names. You no longer have to pay several hosting bills for hosting your websites, DotNetNuke can display the content for each of your domain names from one installation, ie. one hosting account (see figure 2).

How it works (basic steps)

1) Point Domain names to Hosting Providers’ server (This has been done. Check technokelvin.net to prove I could atleast do something right)
Purchase your domain names from a domain name registrar and point the domain names to your hosting providers’ server (using the DNS settings). Read this tutorial for further information: How to adjust your Nameserver settings.

2) Point Domain Names to your single DotNetNuke Installation (I doubt I have access to that but if my technokelvin.net/dotnetnukev4 works didn't they already point the domain name to the IP address of my DNN installation? Or does my domain djcheeks.com have a different IP address for my DNN installation?)
In your Hosting Providers control panel, go into the IIS settings and adjust the Host Header settings to point the domain name to the IP address of your DotNetNuke installation. We explain how to do this in this video tutorial.

3) Create portals in DotNetNuke (I've done with but the the portal alias does not pick up the domain name and point it to the correct portal. Only the one I cannot edit, the one made during installation, points to an actual DNN page. The two portal alises I made, djcheeks.com and even technokelvin.net both point back to my web host, not DNN)
In DotNetNuke create multiple portals for each of your domain names. The Portal Alias settings pick up the domain name and point it to the correct portal. We explain how to do this in this video tutorial.

Can anyone help, even a little bit? A URL? Tutorial? Guide? Advice? Solution? If it's the host then a better one that supports DNN and has a reseller program?

Anything will be greatly appreciated.

Thank you in advance.
