I am capable of viewing a sample test website that shows the PHP info with the following code: <?php phpinfo(); ?> Now that this works I tried to migrate my PHP website to IIS6 and here is a list of the errors/warnings I got: PHP Warning: session_start(): open(C:\WINDOWS\Temp\sess_rjbv0ialf7uf03to69q1e4l101, O_RDWR) failed: Permission denied (13) in C:\Site\index.php on line 11 PHP Warning: Unknown: open(C:\WINDOWS\Temp\sess_rjbv0ialf7uf03to69q1e4l101, O_RDWR) failed: Permission denied (13) in Unknown on line 0 PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (C:\WINDOWS\Temp) in Unknown on line 0 After seeing this, I corrected the php.ini file to set correctly the session date value: session.save_path="C:\WINDOWS\Temp" Yet doing so has done nothing!
