[SOLVED] admin page URL fails but www.domain.tld goes to ispCP login

[Rusted]

Right, I have public DNS for http://www.domain.tld but not for admin.hostname.domain.tld. I have a local host file entry for that. Still, http://www.domain.tld resolves to the panel not to the virtual site. If I use a host file entry for http://www.domain.tld pointing to the internal address, I still get the panel. Seems to be an issue with the server resolving the virtual URL.

Am I way off?

I greatly appreciate your help! Would I be better off rebuilding with a different domain name for the server than I am using for the virtual site?
