setting default homepage

I have a window 2000 system with a local security policy which doesnt let people do anything but surf the net. Somehow someone changed the default homepage. I don't know how they did it because it is pretty secure. I tried the link at the bottom of www.searchnow.ws and it didnt work. It just refreshed the page.
¿¿¿¿does anyone know how to set a page to be the default automatically when the pages load????...I want to see if there is a loophole past my security settings. I know there must be a ton of jscript and other code that can do this.
Thanks
