note 29872 rejected from function.session-name by betz

I am running PHP on PWS on Win98 platform. And I am testing using session_start() function. Unfortunately, the error shown as follows: Warning: session_start() [function.session-start]: open(/tmp\sess_742a0036678927d4f904cdc669c2b270, O_RDWR) failed: No such file or directory (2) in C:\Inetpub\wwwroot\Validate.php on line 11 Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Inetpub\wwwroot\Validate.php:6) in C:\Inetpub\wwwroot\Validate.php on line 11 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Inetpub\wwwroot\Validate.php:6) in C:\Inetpub\wwwroot\Validate.php on line 11 How can I resolve this. Is this because I did not end the previous session? How could I end the previous session? Thank you for your help. Regards, AST
