It would seem to be a logon attempt from an account that does not exist. Is there a scheduled task or service set to run under an account which has been deleted ?

All  - I found a hint in the second link sk raja raja sent about Stored User Names and Passwords.  I added a user account and this eliminated the event id 40960.
