SQL Server Alert System: Demo: Sev. 24 Errors - Login failed ,,,

  • Hello,

    MSSQL 7 w/SP2; Win NT

    The 'sa' account was changed about 2 months ago. The SQLServerAgent account is not operating uder 'sa'. There are no jobs owned by 'sa'. Backups are successful and 10 GB disk remains. The error messages began just 2 days ago, and the repeat frequency has increased from every hour to every 1-2min. Can anyone shed some light on the following:

    <for each occurance> ...

    The MSSQL errors logs:

    * <date> <source=logon>  Login failed for user 'sa'.

    The opeartor receives the following 2 emails:

    * SQL Server Alert System: 'Demo: Sev. 24 Errors' occurred on "\\servername"

    DESCRIPTION: 18456

    Login failed for user 'sa'.

    * SQL Server Alert System: 'Demo: Sev. 22 Errors' occurred on \\servername

    DESCRIPTION: 18456

    Login failed for user 'sa'.

    Windows Event Viewer:

    18456 : Login failed for user 'sa'.

    Many thanks. Jeff

  • Either one of two things is happening:

    1.  You still have a job or an application running that is attempting to login using the sa account, and fails.

    2.  Someone is trying to hack you sa account.

     

    I would just run profiler and find out where these requests are coming from?

  • Turned out to be #2 ... we used a network IP sniffer to block. Thanks for the advice.

    Many thanks. Jeff
