Repeated Login failed for user SA in Event Log.

At regular intervals there are failed login message for User SA, User User,
User Root in the event log. This seems to have started after Security Patche
s
were applied.
How do I stop these failed logins occuring?
Thanks

Try changing SQL Agent to use Windows Authentication instead of Standard
