newbie: virtualhost

Hi

I have installed a webserver (wampserver). I have played around with
virtualhost and all works well....if it is on the same machine.

Now I want the webserver (192.168.2.5) being able to acces a directory on a
different machine (192.168.2.3) where the files of a website are located.

Both machines WXP.

I tried changing settings in httpd.conf en HOSTS but I don't get it to work.
Can anyone help?
I probably have to do something on the other machine as well. However I
don't know what!

Thanks in advance.
