My heartiest thanks in advance for the replies :)

Answer 1

So I just had the same issue on my server after changing the password for the account that the tasks were run under. To solve I made a change to the task settings that required me to re-enter the account password.

Answer 2

I had the same issue with the same error code. You can have a try on change following. === quote start === in task scheduler, click on the scheduled job properties >>> then settings

in the last listed option: "if the task is already running, the following rule appplies:" select "stop the existing instance" from the drop down list.
