XAMPP across local network help please

[StrangeRanger]

Hi,
I'm running xampp 1.7.3 on an XP machine. It works perfectly on my local machine, but when I try to access it across our local network all I get is the xampp welcome/home page.
I've been reading for hours and have tried everything I've seen suggested including changing the various .conf files, checking port forwarding etc.
I don't understand why across the newt work I can see the "home page" but not access anything else. Can someone please suggest something else for me to try?
Thank you,
