This simple command allows you to get the GPO GUID in your Active Directory domain. Since Windows 2012, you can use the cmdlet get-gpo to play with Group policies
get-gpo -all | select id
Reference
Gets one GPO or all the GPOs in a domain.
Syntax
Get-GPO [-Name][-Domain ] [-Server ] [ ]
Get-GPO -Guid[-Domain ] [-Server ] [ ]
Get-GPO [-All] [-Domain] [-Server ] [ ]
Detailed Description
The Get-GPO cmdlet gets one GPO or all the GPOs in a domain. You can specify a GPO by its display name or by its globally unique identifier (GUID) to get a single GPO, or you can get all the GPOs in the domain by specifying the All parameter.
The Get-GPO cmdlet returns one or more objects that represent the requested GPOs. By default, properties of the requested GPOs are printed to the display; however, you can also pipe the output of the Get-GPO cmdlet to other Group Policy cmdlets.
Parameters
-All
Retrieves all the GPOs in the domain.
Attributes
| Name | Value |
|---|---|
| Required? | false |
| Accept wildcard characters? | false |
| Accept Pipeline Input? | false |
| Position? | named |
-Domain
Specifies the domain for this cmdlet. You must specify the fully qualified domain name (FQDN) of the domain (for example: sales.contoso.com).
For the Get-GPO cmdlet, the GPO (or GPOs) to retrieve must exist in this domain.
If you do not specify the Domain parameter, the domain of the user that is running the current session is used. (If the cmdlet is being executed from a computer startup or shutdown script, the domain of the computer is used.) For more information, see the Notes section in the full Help.
If you specify a domain that is different from the domain of the user that is running the current session (or, for a startup or shutdown script, the computer), a trust must exist between that domain and the domain of the user (or the computer).
You can also refer to Domain by its built-in alias, “domainname”. For more information, see about_Aliases.
Attributes
| Name | Value |
|---|---|
| Required? | false |
| Accept wildcard characters? | false |
| Accept Pipeline Input? | false |
| Position? | named |
-Guid
Specifies the GPO to retrieve by its globally unique identifier (GUID). The GUID uniquely identifies the GPO.
You can also refer to the Guid parameter by its built-in alias, “id”. For more information, see about_Aliases.
Attributes
| Name | Value |
|---|---|
| Required? | true |
| Accept wildcard characters? | false |
| Accept Pipeline Input? | true (ByPropertyName) |
| Position? | named |
-Name
Specifies the GPO to retrieve by its display name.
The display name is not guaranteed to be unique in the domain. If another GPO with the same display name exists in the domain an error occurs. You can use the Guid parameter to uniquely identify a GPO.
You can also refer to the Name parameter by its built-in alias, “displayname”. For more information, see about_Aliases.
Attributes
| Name | Value |
|---|---|
| Required? | true |
| Accept wildcard characters? | false |
| Accept Pipeline Input? | true (ByPropertyName) |
| Position? | 1 |
-Server
Specifies the name of the domain controller that this cmdlet contacts to complete the operation. You can specify either the fully qualified domain name (FQDN) or the host name. For example:
FQDN: DomainController1.sales.contoso.com
Host Name: DomainController1
If you do not specify the name by using the Server parameter, the PDC emulator is contacted.
You can also refer to the Server parameter by its built-in alias, “dc”. For more information, see about_Aliases.
Attributes
| Name | Value |
|---|---|
| Required? | false |
| Accept wildcard characters? | false |
| Accept Pipeline Input? | false |
| Position? | named |
-CommonParameter
This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see About Common Parameter
Input and Return Types
The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet emits.
| Input Type | Microsoft.GroupPolicy.Gpo. A GPO for which to get information. You can pipe GPO objects into this cmdlet to display information about the GPOs. Collections that contain GPOs from different domains are not supported. |
| Return Type | Microsoft.GroupPolicy.Gpo. Get-GPO returns an object that represents the requested GPO. |
Notes
-
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 example, 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 execute 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 executed from a startup or shutdown script, the default domain is the domain to which the computer is joined.
Only one domain can be used by an instance of this cmdlet. If you pipe a collection of GPO (Microsoft.GroupPolicy.Gpo) objects to this cmdlet, the DomainName property of the first GPO object in the collection specifies the domain for the cmdlet. (This is because “domainname” is a built-in alias for the Domain parameter, and the Domain parameter can take its value by property name from the pipeline.) A non-terminating error occurs for any GPOs in the collection that are not in this domain. If this domain is different from the domain of the user account (for startup or shutdown scripts, the computer account), a trust must exist between the two domains.
Examples
EXAMPLE 1
C:\PS> Get-GPO -name "Group Policy Test" DisplayName : Group Policy Test DomainName : contoso.com Owner : CONTOSO\Domain Admins Id : 31a09564-cd4a-4520-98fa-446a2af23b4b GpoStatus : AllSettingsEnabled Description : CreationTime : 2/26/2009 12:15:42 AM ModificationTime : 2/26/2009 12:15:42 AM UserVersion : AD Version: 0, SysVol Version: 0 ComputerVersion : AD Version: 0, SysVol Version: 0 WmiFilter :
Description
———–
This command retrieves the “Group Policy Test” GPO. The GPO must exist in the domain of the user that is running the session (or, for startup and shutdown scripts, the computer). The command retrieves the GPO information by contacting the primary domain controller (PDC).
EXAMPLE 2
C:\PS> Get-GPO -Guid 31a09564-cd4a-4520-98fa-446a2af23b4b -Domain sales.contoso.com DisplayName : Group Policy Test DomainName : sales.contoso.com Owner : SALES\Domain Admins Id : 31a09564-cd4a-4520-98fa-446a2af23b4b GpoStatus : AllSettingsEnabled Description : CreationTime : 2/26/2009 12:15:42 AM ModificationTime : 2/26/2009 12:15:42 AM UserVersion : AD Version: 0, SysVol Version: 0 ComputerVersion : AD Version: 0, SysVol Version: 0 WmiFilter :
Description
———–
This command retrieves the GPO that has the ID (GUID) 331a09564-cd4a-4520-98fa-446a2af23b4b in the sales.contoso.com domain. If the domain of the user that is running the session (or, for startup and shutdown scripts, the computer) is different that sales.contoso.com, a trust must exist between the two domians. The command retrieves the GPO information by contacting the PDC (in the sales.contoso.com domain).
EXAMPLE 3
C:\PS> Get-GPO -All -Domain sales.contoso.com
Description
———–
This command retrieves all the GPOs in the sales.contoso.com domain.
