Yes I ' v created a new file and then copied your code.

Then i modified this:

require("forum/global.php");

and test it.

This is the result:
Warning: Undefined variable: REQUEST_URI in C:\Inetpub\wwwroot\swzone.it\forum\global.php on line 33

Warning: Undefined variable: QUERY_STRING in C:\Inetpub\wwwroot\swzone.it\forum\global.php on line 41

Warning: Undefined index: HTTP_POST_VARS in C:\Inetpub\wwwroot\swzone.it\forum\global.php on line 58

Warning: Undefined index: action in C:\Inetpub\wwwroot\swzone.it\forum\global.php on line 58

Fatal error: Failed opening required './admin/config.php' (include_path='') in C:\Inetpub\wwwroot\swzone.it\forum\global.php on line 66

My server (I host directly) is an IIS5 with Php 4.0.6
Thx for your interest
