Getting Www.domain.com To Work, Domain.com Resolves Correctly, Just Not With Www

Okay guys, a quick question for all the gurus out there. I'll admit I'm a bit embarassed posting such an easy question, but give a guy a break, I've been using managed servers for god knows how long and I've finally decided to take a dive into administration. Everything is firewalled and secured properly, I'm just having trouble getting the ServerAlias to work right.

What happens is I go into my browser and enter in [url]walaa! It works.

Now, when I enter in [url], it does not resolve.

I have checked with "dig" the domain settings and it looks as though all of the nameservers are set up fine, this is an apache problem. I'm running apache 2.2 on Ubuntu 7.10 for all those who are interested.

Here is my etc/apache2/sites-available/domain.com:

<VirtualHost *:80>

# Admin email, Server Name (domain name) and any aliases
ServerAdmin webmaster@domain1.com
ServerName domain.com
ServerAlias www.domain.com

# Index file and Document Root (where the public files are located)
DirectoryIndex index.html
DocumentRoot /home/demo/public_html/domain.com/public

# Custom log file locations
LogLevel warn
ErrorLog /home/demo/public_html/domain.com/logs/error.log
CustomLog /home/demo/public_html/domain.com/logs/access.log combined

</VirtualHost>

I've been messing with it for about 45 minutes and I'm worn out at ~4:30am and could use a helping hand from the pros.
