Failed Authentication Attempts

  • Is there a way in SQL Server 2000, to check within a given time frame if there have been any connection attempts that did not pass authentication?

    If there is, does the method work for 2005 as well, or is there a different way to check there?

    Thanks,

    Chris

  • Set the Audit level to "All" in SQL Server 2000 and "Both Failed and Successful logins" in SQL Server 2005. After restarting the services, you can see both failed and successful login attempts in the SQL Server Error Logs.
