Wordpress help needed

[Ward Hills]

As I mentioned last Friday I have a technical issue with a multisite instance of Wordpress.  All the sites appear as subdomains eg.  domain.com   and  something.domain.com.  I want it to be domain.com and something.com

Specifically, it is wardhills.net and officehoursgroup.net that I am trying to get to.  Now officehoursgroup.net  is resolving to officehours.wardhills.net

Any help appreciated!
