Configuring Subdomains for all Packages

[slashpen]

How do I make subdomains work for instantly for all packages and accounts?
This is a new webserver. By the defaults all work fine but notice that the subdomain aren't working.
I added a subdomain using the Cpanel and it was successfully added. I also see it listed in WHM and a folder inside public_html.

The problem is that I can't access the subdomain via subdomainname.domain.com.....
How do I make this right in WHM? so that in the feature all packages or accounts in WHM will work with subdomains...?
Please help... thanks

Kindly be specific in step by step since I'm really a newbie... thanks

Are they working now? Adding a subdomain makes a change to the domains named file and changes to it can take time to be noticed.

I've successfully added the subdomains using Cpanel and it is also listed in the WHM list of subdomains. The problem is I can't access it "Page not found".
It's already more than a week since the subdomain was added....

Are you a reseller or server owner? Do you have root access to the server?

Take a look at the domains zone file, (/var/named/domain.com.db), and see if there is an entry like this:

subdomain 14400 IN A xxx.xxx.xxx.xx

If so, take a look at your httpd.conf file to verify an entry for the subdomain in there.That's probably at /usr/local/apache/conf/httpd.conf, but depends on your server.
