windows server 2012 Event id 4979 - An attempt was made to query the existence of a blank password for an account.

When I log in to the window server 2012. the account may trigger the server to query the existence of a blank password for all of the local account in the server (Event ID 4979)

In the security event log, there will be a list of action logged to indicate that my account queried the existence of a blank password for all of the local account in the server.


What are the causes to lead this abnormal action?


As the query actions are not triggered every time when I log in the server. There is only some chances to trigger the action.

What condition will trigger the account to query the existence of a blank password for all of the local account in the server ?


Are there any security issues for the query action?


Thanks.
