As long as your a customer of SITEBIZ you will have two websites LIVE (Production) and a DEV (Developmental) machine.
Accessing your ADMIN PANEL on the development server is slightly different then accessing the live site ADMIN PANEL.
Your domain will be at the front of the URL if your domain name is sitebiz.com then just drop the extension and put the top level at the front of the url.
The ADMIN panel is going to be the same for live except that you will use your actual domain.
** If you would like to change the secureadmin page url to something else you can using the admin - please let us know if you do that.
