530:
Logon Failure - Account logon time restriction violation
On this page
The logon failed because the user attempted to log on outside the account's hour or day of week restrictions. To determine if the user was present at this computer or elsewhere on the network, see the Logon Types chart in event 528.
Event 530 is logged on the workstation or server where the user failed to log on. Event 530 is logged on a domain controller 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, event 530 will be generated only by an attempt to log on with a domain account; local accounts do not offer time restrictions.
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.
