I setup the Wordpress Multisite on an existing site, all

I setup the Wordpress Multisite on an existing site, all seemed to work fine, while waiting for propogation apx 10 mins later my browser reads "This Webpage Not Available" . I can access cpanel for the site and if I reset the DNS zone via WHM it shows back up an hour later, otherwise the site and Wordpress are not accessible. Any idea what would cause that?

Thx
