Hhm... Check your Special:Version. If it says "fast-cgi" or any other thing mentioning "cgi" for your PHP, then you have Windows IIS. I don't know about it, but GoDaddy just might restrict the required functions, as many webhosts tend to do so, but I doubt that for such a basic and fundamental function like the randomization functions.
