DNS issue when removing single site from multisite

I looked through about every link I could find, but they were WP specific issues. This is more of a DNS issue.

I have a multisite setup that I had a lot of fun setting up, but now I realize my sites are too different, and I need to make them individual sites and shut the multisite install down.

It is a “subdomain” install.

The problem is that when I try to use cpanel to create a new user, the DNS stuff tells me that the domain is already setup.

This new “individual” account is actually on the same reseller account at HostGator.

The problem is that once I have done everything to the DNS settings that I know how, the domainname newsite.com still points to the multisite install at oldmultisite.com.

Then I get this screen that says “Greetings Site Administrator! You are currently allowing “none” registrations. To change or disable registration go to your Options page.
Registration has been disabled.”

Since this first site has low traffic and it is for my son’s project, I left the DNS like that all night and nothing.

Then this morning I just went into the WP settings on the multisite and changed the domain mapping to map newsite.com back to it’s place on the multisite, and everything is pointing to multisite and the site pops back up.

The problem is that I want it to be an individual site not a multisite.

Should I post the domain names here or in a PM so that you can see what I have?

SO, the question is:

Does anyone know how I should setup newsite.com so that it goes to newsite.com?

Thanks a ton,

James
