The control panel used by ServInt requires that a subdomain be used as the primary account name. This subdomain is used to register the control panel, and alternately as one way for ServInt to uniquely identify each server. cPanel/WHM in particular has documented problems when users utilize “www” as a third-level domain. This requires that customers alternate subdomains, such as vps.mydomain.com, server.mydomain.com, or any third-level domain other than www.mydomain.com. Of course, you will still be able to configure www.mydomain.com in your web server.
