subdomain creation help

[blckspder]

Hello,
I have setup a webserver with fedora 7, Everything seems to be working fine, but I am trying to add a sub domain and it doesnt seem to be working, I added it to the httpd.conf file as a virtual host nd I updated my hosts file as well... Perhaps I should be adding it somewhere else? or I have something configured incorrectly?

My domain is www.sono-test.com
the subdomain I want is panel.sono-test.com

The sub domain works if I am on the server itself accessing the web, if I use a regular client computer or I am outside the network I can't get to the subdomain.

Please let me know and thanks for the help.

Here is what my conf file looks like for virtualhosts

NameVirtualHost [myInternalIPAddress]:80
<VirtualHost www.sono-test.com:80>
ServerAdmin asousa@sono-tek.com
ServerName www.sono-test.com
ServerAlias sono-test.com
DocumentRoot /var/www/html/sono-tek.com
ErrorLog /var/www/error/error.log
CustomLog /var/www/error/access.log common
</VirtualHost>
<VirtualHost panel.sono-test.com:80>
ServerAdmin asousa@sono-tek.com
ServerName panel.sono-test.com
ServerAlias panel.sono-test.com
DocumentRoot /var/www/html/sono-tek.com/controlPanel
ErrorLog /var/www/error/error.log
CustomLog /var/www/error/access.log common
</VirtualHost>

Like I said if I am acutally on the server, surfing the web I can see the subdomain page, but if I am on another computer or outside the network I can't, So i think it might be a DNS problem maybe, if anyone has any ideas let me know. thanks

It is a DNS problem, there isn't a DNS record for panel.sono-test.com.
