Task Scheduler failed to start. Additional Data: Error Value: 2147943726

After reading this post this is what worked for me. Go to properties of task Under General tab, at the bottom of that window you will see Configure for: Change that to the system you are using (in my case server 2012 R2) hit ok and enter your password.

I had to select the option to "Do not store password. The task will only have access to local computer resources.", which was fine based on what the task was defined as. For me, I suspect some sort of recent patch or security hardening caused this as it seemed to move through our environments at similar but different days.

Today I got the same problem, (HRESULT) 0x8007052e (2147943726) "unknown user name or bad password"

My solution: was to Re-Asign the User on the "Change User or Group" button to get the lattest Active Directory information of the User.

Then I could Run the Task Again...

As a better practice, you could use an "Aplicative" User instead of a regular User which change more often in regular basis.

If you use your account, it may change your password every some quantity of days... and you will need to "fix it" again...

If you use an "Aplicative" account, it may change less than regular User...

You could do this by going to the task tab "General", then "Change User or Group" and assigning the "Aplicative" account, then "OK" Button.

I had the same issue with the windows task scheduler.

The reason for the failure is the recent change in the password of the system user which was configured at the time of task creation.

Solution:

• Go to properties of task
• Under General tab, click on "Change User or Group..."
• Enter the username in the field "Enter the object name to select"
• This will ask for Authentication, provide your credentials

Thats it !
