533: Logon Failure - User not allowed to logon at this computer

On this page

Event 533 is logged on the workstation or server where the user failed to logon. To determine if the user was present at this computer or elsewhere on the network, see the Logon Types chart in event 528. This event is logged on domain controllers only when a user fails to log on to the domain controller itself (such as at the console or through failure to connect to a shared folder). On workstations and servers, this event will be generated only by an attempt to log on with a domain account; local accounts do not offer workstation logons.

To identify the source of network logon failures, check the Workstation Name and Source Network Address fields.

Logon Process and Authentication Package will vary according to the type of logon and authentication protocol used.

Logon Type: See the chart in event 528.
