Raf This information is logged in the Event Viewer. Open Control Panel, select Classic View on the left side menu. Double click Administrative Tools and double click Event Viewer. In the Event Viewer, expand Windows Logs and select Security. There is a lot of information in this log. The easiest way to see the Log On/Log Off events is to first save the log as a text file. Right click Security and select 'Save Events As...' In the Save As dialog box, select Textin the Save As Type menu. Type a name for the file and save it to the desktop or one of your User folders. Open the file from where you saved it. The Log On events are, Event ID: 4624 The Log Off events are, Event ID: 4634 You can use the 'Find' function in your text editor to pinpoint these events.. The log on event will have the following information.
