Symptoms
Consider the following scenario:
-
You have an enterprise that has a user account lockout threshold policy applied.
-
You create a new task in Task Scheduler. When you create the task, you select the Run whether user is logged on or not option, click to clear the Do not store password. The task will only have access to local computer resources check box, and then click OK to apply the settings.
-
You are prompted to provide the credentials of the user in whose context the task should run.
-
You provide an invalid password several times at the task scheduler authentication prompt.
In this scenario, the user account is unexpectedly locked out.
Note This problem may occur even though the lockout threshold is not reached. This problem may also occur after you update the user account of an existing task.
This problem is related to the problem that is described in the following article in the Microsoft Knowledge Base:
2548120 Account is incorrectly locked after you create or change multiple scheduled tasks in Windows 7, in Windows Server 2008 R2, in Windows Vista, or in Windows Server 2008
Note If you do not have update 2548120 installed, the account can be unexpectedly locked out in even fewer attempts to provide an invalid password.
Cause
very time that you provide an incorrect password for the single task scheduler authentication, the badPwdCount attribute is incremented incorrectly two times (or four times, if update 2548120 is not installed).
Resolution
To resolve this problem, apply the hotfix that is described in that article after you apply update 2548120.
