Task scheduler error 2147943726 is the most common error during task execution. The error is directly related to the inability to start the task. Sometimes the error code is accompanied by the “unknown username or incorrect password” error. This error is only related to the username or password that the task is configured for.
Reasons for Task Scheduler Error 2147943726
The most common reason is if the user's password has changed. The task is configured with the old password.
Sea cual sea el caso, en un caso determinado, aparecerá el mismo error si el programador de tareas ha perdido la confianza en el campo. En esta circunstancia, los errores solo contienen el código de error 2147943726 y no se muestra el error «Nombre de usuario desconocido o contraseña incorrecta».
Reassigning the user to an application account
The vast majority of users who encountered this issue reported that the issue was resolved after reassigning the user to the latest Active Directory data of the user in (Change user or group).
If you want a long-term solution, you should use an "app" user instead of a regular user that changes regularly. If you use your account, you can change your password from time to time, which means you'll need to reapply this fix.
But if you use an "application" account, the response you're going to implement will most likely last until the next Windows installation.
Re-authenticate access
The reason for the failure is the most recent password change of the system user that was set when the task was created.
- Go to task properties
- On the General tab, click “Change user or group…”.
- Enter the username in the "Enter the name of the object to choose" field.
- This will require authentication, please specify your credentials.
