ConfigMgr 1906 Hotfix KB4529824 – Message Processing Engine Update

There is a new ConfigMgr 1906 Hotfix KB4529824 available for the Message Processing Engine component of the SMS Executive service. This hotfix or update is applicable only for Configuration Manager version 1906.

The previous SCCM 1906 hotfix release was KB4529827. However a lot of users had issues in downloading the update. If you are unable to download the SCCM 1906 hotfixes, read this post.

The hotfix KB4529824 resolves the following issues.

  • In SCCM 1906 setup where the site server and SQL server are using a non-US English date format (mm/dd/yyyy), Active Directory User Discovery may fail to add records as expected. You see the below errors logged in SMS_Message_Processing_Engine.log file.
ERROR: Got SQL exception when handle discovery message. Exception: System.Data.SqlClient.SqlException (0x80131904): Converting a type of nvarchar data to datetime data type has created an out-of-bounds value
  • Active Directory user discovery will fail to add new records if a custom date/time field is added, such as “whenChanged”. You can find the below errors logged in SMS_MESSAGE_PROCESSING_ENGINE.log file.
ERROR: Got non retryable invalid data exception when process message {guid}. Exception: System.IO.InvalidDataException: Invalid client report time

Most of all, if you are running Configuration Manager 1906 and if you notice the above errors in your setup, you must install this hotfix. Otherwise you can skip installing this hotfix or upgrade to Configuration Manager 1910. Read more about the hotfix here.

Before you install the KB4529824, you must first install KB4529827 because that’s the prerequisite. You don’t have to restart the computer after you apply this update.
