how can i keep track when people log on and off windows xp?

Question

well someone where i heard something in event veiwer but it didnt show anything about people logging on and off

Answer 1

In the Event Viewer there's a log for Application and one for System (sometimes others). Look for a block of entries that are all entered around the same time. Those are typically a sign of a boot up.

Some of those entries will be applications or services that are started up under the user account. Those ones will show the user's name in the User column, so you can tell who logged in.
