4800: The workstation was locked

On this page

When either a user manually locks his workstation or the workstation automatically locks its console after a period of inactivity this event is logged.

To find out when the user returned and unlocked the workstation look for event ID 4801.

If a screen saver is used, there is a relationship between this event and 4802/4803  See event ID 4802 for an explanation of the sequence of events.
