An error occurred when storing the task sequence

I came across the above error today whilst editing task sequences with System Center 2012 Configuration Manager SP1 integrated with MDT 2012 Update 1. After adding in an additional task sequence step and clicking the Apply or OK button, a message box appeared displaying the message “An error occurred when storing the task sequence”. Initially I thought I had configured something incorrectly within the task sequence step, however after some testing, I found I couldn’t even add a simple step such as the “Restart Computer” step.

After reviewing the SmsAdminUI.Log, I discovered the following error message:-

Description = “Invalid sequence input parameters – task sequence not found.”;
ErrorCode = 1078462229;


  1. Close the Configuration Manager Console.
  2. Restart the Windows Management Instrumentation service (and required dependencies) on the SMS provider Computer.
  3. Open the Configuration Manager Console.

You should now be able to edit and save task sequences.
