My subdomains get directed to another website

I have installed MU word press.

I have successfully added the multi user snip it that allows the tool-netork option appear.

I then added the code to the wp-config and .htaccess files.

Now, when I try to access either of the subdomains, I get a different website hosted on the same VM.

example:

http://www.domain.com
sub1.domain.com
sub2.domain.com

the sub1 and sub2 always go to a totally different site:

domain2.com

that is hosted on the same server.

Ideas?
