Windows 2000 auditing

I have windows 2000 auditing turned on. However, it is not giving me the information I am looking for. I want to be able to pull up usage by user id. I need information such as dates the user logged in and how long the user was connected. I need to compile this data over several days. I would like to run a report on Monday mornings and have several users per report. On the report I need to have the dates and times and length of time the users were connected to the LAN. I need this to audit my remote users who connect to my LAN via VPN throught the Windows 2000 RAS server. Any ideas?
Thanks,
Scott
