Domain problem

[Wiz]

Hi!

I have installed ispcp on a fresh Debian 5 os.
I don't know how to setup my default domain name.

So my hostname are: blabla.domain.com, and my default domain are: domain.com

How can i setup domain.com?

The ispcp panel works with admin.domain.com, but i can't acces to domain.com




EDIT: I have reinstalled debian +ispcp and now my control panel shows on admin.domain.com and domain.com too...

Help me!
