During the creation of a scheduled task using the task scheduler of Windows Server 2008 R2, I got the following error:
Error has occurred for task ‘TaskName’. Error message: User account restriction error. The possible reasons are that blank passwords not allowed, or that a policy restriction has been enforced.
and I couldn’t save the task….
Since you can choose a user to execute the task, the problem was that the chosen user had a password too short, that violated system policies about password complexity.
I changed the password of the user and tried to save the task again using that user.
This time I was able to do that!
