"Login failed for user" error occurs when run Maintenance plan with SQL login account in SQL Server 2016 RRS feed

  • Question

  • Hello,

    Recently, I have upgrade from SQL Server 2008 to SQL Server 2016,

    After the upgrade, I encountered a bug which the symptom is exactly match the below link:


    From the link, we know that this bug is fixed in Cumulative Update 5 for SQL Server 2016 SP2

    However, I still encounter the same problem with Cumulative Update 13 for SQL Server 2016 SP2

    The bug I faced is occurred when I use [sa] account, if I replace it with windows account in backup job, then there is no more messages.

    Anyone is facing the same problem and have idea to solve it?

  • We should avoid using old method of Maintenance Plan. Create an SQL Job for your Backup tasks and then it is easy to monitor, maintain and track.

  • Hi,

    you can use the scripts from Ola Hallengren


    He did a good job for maintenance scripts.

    Take a look and you'll be happy.

    Kind regards,

  • Hi Matthew,

    As normal, it should be fixed after upgrading to the CU5 SQL Server 2016 or later.

    Could you please have a try to restart the SQL Server service or even server and check again?

    Please try to disable the option to "Enforce password policy" for the sa account and check whether this could be hepful to you.

    In addition, I could not reproduce this issue from my side.
