Applies To: Windows Vista, Windows Server 2008, Windows 7, Windows 8.1, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2012, Windows 8

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.

Constant: SeDenyBatchLogonRight

Possible values

• User-defined list of accounts

• Not defined

Best practices

1. When you assign this user right, thoroughly test that the effect is what you intended.

2. Within a domain, modify this setting on the applicable Group Policy Object (GPO).

3. 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.

Location

GPO_name\Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment

Default values

The following table lists the actual and effective default policy values for the most recent supported versions of Windows. Default values are also listed on the policy’s property page.

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.

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:

1. Local policy settings

2. Site policy settings

3. Domain policy settings

4. 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.
