auditing

Hello
I am using windows 2000 professional (Personal Computer).
How can i audit these events
User logon
user logoff
restart and
shutdown
Enabling the audit policies it only audits user logon (event ID 528)

I want to track that “how much (time) a user uses the computer
in a day.Any thing else that can be used, any tool (3rd party )

Please Help me.
Thanks.
