[edit] What you should do
This means that the account has been locked out by Windows, typically because of too many authentication failures. This may indicate that the account is under attack, and the source(s) of the logon failures should be investigated to determine if this is an attack against other accounts. Search the GUI for additional events from the source IPs for these events.
The platform will track this logon, and if multiple events occur will issue a higher level alert that a brute force attack may be occurring.
