Complicated Hosting Problem

I finally have Cpanel functioning pretty much (thank you carl), but a whole nother problem has presented itself.

Before I installed Cpanel, I was hosting a domain on this server (apache vhost) and it was complicated but I got the vhost to work.

hostname.com would goto the server's home page (for teachers, i work for school system)

mydomain.com would goto my website

All was fine and dandy.

Now, I add my domain to cpanel and it takes over my hostname.
So mydomain.com works, but hostname.com goes to mydomain.com

So.. Complicated problem gets even worse.. How do I add users to hostname.com? I can only add subdomains to mydomain.com

Do I need dual NICs or something?

I'm soooo lost

 

bump?

 

It was a clean install -- but before i had reinstalled redhat I had everything set quite nicely with Apache.

Basically I'm struggling with not being able to add users to my hostname (for teachers accounts), and one domain I had added takes over my hostname page and I dont know how to solve it..

I even got nameserver ips from the ISP, even though I dont know if I need them.

 

Okay,
I fixed the domain taking over the hostname.. but now when I try creating an account like test1.hostname.com

It goes through and creates it successfully; but the account does not work.. like i cannot goto that web address


Any ideas?
