Actually, the web server has something (a lot actually) to do with sessions (in general). Without these sessions working with the web server, you won't get a session however your try. You can try and modify a script a million times, but it still won't work if the web server isn't accepting the session correctly. Apparently, in IIS6, it doesn't seem to accept PHP sessions correctly. If baddai is using an Apache web server, then it should be no problem, but if he's running of an IIS6 web server, he's going to run into problems.
