No go....

I worked out the errors here, but it doesn't actually return an NT login for me... It just returns, "Your login is:03 00."

Code:
<?php
     /*
      Getting netbios info
      CopyLeft 2002 (GNU GPL V2) by polo
     */     
 
     error_reporting(E_ALL);
 
     /* get the ip of the client */
     if (isset($_SERVER["HTTP_X_FORWARDED_FOR"]))
...
