4718: System security access was removed from an account

On this page

This event documents the revokation of logon rights such as "Access this computer from the network" or "Logon as a service".

Rights, like most other security settings, are defined in group policy objects and applied by the computer. Therefore this event will normally show the Assigned By user as the system itself. To determine who actually made the rights assignment change you must search the domain controllers' security logs for changes to groupPolicyContainer objects (logged by Directory Service auditing). Logon ID allows you to link this event to the prior event 4624 logon event of the user who performed this action.

This event, 4718 documents the system name for each logon right as opposed to the more familiar description. Click here for a cross reference.

Note: This event and 4717 log changes to strictly logon rights such as "Access this computer from the network" or "Logon as a service" - not to other rights such as "Change the system time" or "Take ownership of files and other objects". See events 4704 and 4705.
