Description

The Set-GPInheritance cmdlet blocks or unblocks inheritance for a specified domain or organizational unit (OU).

GPOs are applied according to the Group Policy hierarchy in the following order: local GPO, GPOs linked to the site, GPOs linked to the domain, GPOs linked to OUs. By default, an Active Directory container inherits settings from GPOs that are applied at the next higher level in the hierarchy. Blocking inheritance prevents the settings in GPOs that are linked to higher-level sites, domains, or organizational units from being automatically inherited by the specified domain or OU, unless the link for a GPO is enforced.

You use the Target parameter to specify the Lightweight Directory Access Protocol (LDAP) distinguished name of the domain or OU, and use the IsBlocked parameter to specify whether to block or unblock inheritance.

Examples

Example 1: Block inheritance for a OU in a domain

PS C:\> Set-GPInheritance -Target "ou=MyOU,dc=contoso,dc=com" -IsBlocked Yes 
Name                  : myou 
ContainerType         : OU 
Path                  : ou=myou,dc=contoso,dc=com 
GpoInheritanceBlocked : Yes 
GpoLinks              : {TestGPO-1, TestGPO-2} 
InheritedGpoLinks     : {TestGPO-1, TestGPO-2}

This command blocks inheritance for the OU named MyOU in the contoso.com domain. GPOs that are linked to higher-level sites or domains, or to OUs that are parent OUs of the OU named MyOU are not applied, unless their links are enforced, when Group Policy is processed for the OU on the client.

Because inheritance is blocked, only GPOs that are linked directly to the MyOU, and those that are enforced at higher-level containers, appear in the InheritedGpoLinks list.

Example 2: Unblock inheritance for a domain

PS C:\> Set-GPInheritance -Target "dc=northwest, dc=contoso, dc=com" -IsBlocked No

This command unblocks inheritance for the northwest.contoso.com domain. GPOs linked to higher-level sites or domains are applied to this domain when Group Policy is processed on the client.

Example 3: Unblock inheritance for an OU in a domain

PS C:\> Set-GPInheritance -Target "ou=MyOU,dc=contoso,dc=com" -IsBlocked No 

Name                  : myou 
ContainerType         : OU 
Path                  : ou=myou,dc=contoso,dc=com 
GpoInheritanceBlocked : No 
GpoLinks              : {TestGPO-1, TestGPO-2} 
InheritedGpoLinks     : {TestGPO-1, TestGPO-2, Default Domain Policy}

This command unblocks inheritance for the OU named MyOU in the contoso.com domain. GPOs that are linked to higher-level sites or domains, or to OUs that are parent OUs of the OU named MyOU, are applied when Group Policy is processed for the OU on the client.

Because inheritance is not blocked, GPOs that are inherited from higher-level containers appear in the InheritedGpoLinks list (together with GPOs that are linked directly to the OU). For instance, the Default Domain Policy GPO is linked at the domain level.

Parameters

-Confirm

-Domain

-IsBlocked

-Server

-Target

-WhatIf

Inputs

Microsoft.GroupPolicy.Som

This cmdlet takes an object that represents a domain or an OU as input.

Outputs

Microsoft.GroupPolicy.Som

This cmdlet returns an object that represents the domain or OU after the operation is applied. The properties of this object that are displayed by default describe the Group Policy inheritance information for the domain or OU. The GpoInheritanceBlocked property indicates whether inheritance is blocked.

Notes

• GPO links that are enforced cannot be blocked. This cmdlet should be used sparingly. Casual use of this cmdlet can complicate troubleshooting.

  You can use the Domain parameter to explicitly specify the domain for this cmdlet.

  If you do not explicitly specify the domain, the cmdlet uses a default domain. The default domain is the domain that is used to access network resources by the security context under which the current session is running. This domain is typically the domain of the user that is running the session. For instance, the domain of the user who started the session by opening Windows PowerShell from the Program Files menu, or the domain of a user that is specified in a runas command. However, computer startup and shutdown scripts run under the context of the LocalSystem account. The LocalSystem account is a built-in local account, and it accesses network resources under the context of the computer account. Therefore, when this cmdlet is run from a startup or shutdown script, the default domain is the domain to which the computer is joined.
