Can you explain what happens when "it didn't work"? Are you getting error messages, etc?
If it's on a college server running Linux or Unix, it is most likely running Apache as the web server. If the admin won't change settings, you can (sometimes) override settings using .htaccess files and the like. The documentation on www.apache.org
is fairly good for items like this. Of course you'd have to know what settings are different between the two, to know what to try. If the errors suggest a problem with php, you can try running a script that reports phpinfo() on each and compare.
