Session kan ikke starte

Hej..
Jeg kører apache på min egen server, og kører det over localhost..
Er det noget jeg skal ind og ændre i php.ini før det virker med sessions ??

Får følgende fejl når jeg prøver at starte en cookie..

Warning: session_start(): open(/tmp\sess_2a2223e81aa3e18ffe05316de645b9cd, O_RDWR) failed: No such file or directory (2) in c:\apache\htdocs\session1.php on line 3

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at c:\apache\htdocs\session1.php:3) in c:\apache\htdocs\session1.php on line 3

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\apache\htdocs\session1.php:3) in c:\apache\htdocs\session1.php on line 3
Tak for det!
Gå nu videre til seesion2.php
