This security policy reference topic for the IT professional describes the best practices, location, values, policy management, and security considerations for this policy setting.
Reference
This policy setting determines which accounts are prevented from logging on by using a batch-queue tool to schedule and start jobs automatically in the future. The ability to log on by using a batch-queue tool is needed for any account that is used to start scheduled jobs by means of the Task Scheduler.
This policy setting is supported on versions of Windows that are designated in the Applies To list at the beginning of this topic.

Best practices
When you assign this user right, thoroughly test that the effect is what you intended.
Within a domain, modify this setting on the applicable Group Policy Object (GPO).
Deny log on as a batch job prevents administrators or operators from using their personal accounts to schedule tasks, which helps with business continuity when that person transitions to other positions or responsibilities.

Operating system version differences
There are no differences in the way this policy setting works between the supported versions of Windows that are designated in the Applies To list at the beginning of this topic.
Note
This setting is not compatible with computers running Windows 2000 Server with Service Pack 1 or earlier.
Policy management
This section describes features and tools available to help you manage this policy.
A restart of the computer is not required for this policy setting to be effective.
Any change to the user rights assignment for an account becomes effective the next time the owner of the account logs on.
This policy setting might conflict with and negate the Log on as a batch job setting.
Group Policy
On a domain-joined computer, including the domain controller, this policy can be overwritten by a domain policy, which will prevent you from modifying the local policy setting.
For example, if you are trying to configure Task Scheduler on your domain controller, check the Settings tab of your two domain controller policy and domain policy GPOs in the Group Policy Management Console (GPMC). Verify the targeted account is not present in the Deny log on as a batch job User Rights Assignment and also correctly configured in the Log on as a batch job setting.
Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:
Local policy settings
Site policy settings
Domain policy settings
OU policy settings
When a local setting is greyed out, it indicates that a GPO currently controls that setting.
Security considerations
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
Vulnerability
Accounts that have the Deny log on as a batch job user right could be used to schedule jobs that could consume excessive computer resources and cause a denial-of-service condition.
Countermeasure
Assign the Deny log on as a batch job user right to the local Guest account.
Potential impact
If you assign the Deny log on as a batch job user right to other accounts, you could deny the ability to perform required job activities to users who are assigned specific administrative roles. You should confirm that delegated tasks are not affected adversely.
