[ActiveDir] tracking users logon to AD

[Henrique Duarte]

Hello,   Does anyone know how to track user's login/logout/session timeout activity within a Win 2000 Domain?  I know it's possible through group policy but there is a lot of irrelevant information that I would have to filter, and as far as I know I cannot automate the filtering in Windows.  All I  need is a sofware/solution that tells me when user "Joe Bloggs " logged in, logged out, and wether he left his desk for an extended period of time.   Thanks in advance,   -Henrique
