Two things to check:

* Is there any character output in page2.php before the opening <?php ?
This includes *any* whitespace, newlines, etc. If there is, then
session_start() will not work correctly (or at all).

* Do you have cookies enabled on your browser? Check in your browser's
cookie list whether you're getting a PHPSESSID cookie from the domain
your script is running on.
