SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows 7, Windows Server 2008 R2, Windows Vista or Windows Server 2008.
  • The computer has an account lockout threshold policy applied.
  • You create or change multiple tasks in Task Scheduler.
  • You select the Run whether user is logged on or not option and clear the Do not store password. The task will only have access to local computer resources option in these tasks.
  • You click OK to apply the settings.
In this scenario, the account that is used to create or change these tasks is incorrectly locked. Additionally, some security events that have Event ID 4625 and that resemble the following are added to the Security log:

Log Name: Security
Source: Microsoft-Windows-Security-Auditing
Date: <date & time>
Event ID: 4625
Task Category: Logon
Level: Information
Keywords: Audit Failure
User: N/A
Computer: <computer name>
Description:
An account failed to log on.

Account Domain: <name>
Logon ID: <ID>

Logon Type: 4

Account For Which Logon Failed:
Security ID: NULL SID
Account Name: <name>
Account Domain: <name>

CAUSE

This issue occurs because the Task Scheduler service unnecessarily tries to register the task by using a NULL password.

When the account lockout threshold is reached, the user account is locked.
