No, this setting does not affect the reading of Event Logs by LANGuardian.

The 'update once per week' setting causes LANGuardian to check for any changes to the directory at the interval specified; changes such as new users being added, or a users email address being changed. It does not control how LANGuardian queries for User Logon Events. LANGuardian can operate quite happily without these updates, they just allow the system to generate more complete reports.

The User Logon Event information is read from the Event Security Log by LANGuardian once every 5 minutes or so. We recommend that the Event Log settings be changed to 'overwrite old events as required' and have a minimum logfile size of 16MB, to ensure all relevant events are available for LANGuardian to read them.

Events such as File Accesses are generated from Deep Packet Inspection of the network traffic and are unaffected by any of these settings.
