Description

The Restore-ADObject cmdlet restores a deleted Active Directory object.

The NewName parameter specifies the new name for the restored object. If the NewName parameter is not specified, the value of the Active Directory attribute with an Lightweight Directory Access Protocol (LDAP) display name of msDS-lastKnownRDN is used. The TargetPath parameter specifies the new location for the restored object. If the TargetPath is not specified, the value of the Active Directory attribute with an LDAP display name of lastKnownParent is used.

The Identity parameter specifies the Active Directory object to restore. You can identify an object by its distinguished name or GUID. You can also set the Identity parameter to an object variable such as $<localObject>, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-ADObject cmdlet to get a deleted object by specifying the IncludeDeletedObjects parameter. You can then pass the object through the pipeline to the Restore-ADObject cmdlet.

Note: You can get the distinguished names of deleted objects by using the Get-ADObject cmdlet with the IncludeDeletedObjects parameter specified.

Examples

Example 1: Restore an object and set attributes for the deleted object

PS C:\> Restore-ADObject -Identity "613dc90a-2afd-49fb-8bd8-eac48c6ab59f" -NewName "Kim Abercrombie" -TargetPath "OU=Finance,OU=UserAccounts,DC=FABRIKAM,DC=COM"

This command restores the ADObject while setting the msDS-LastKnownRDN attribute of the deleted object to the NewName parameter and setting the lastKnownRDN to the TargetPath parameter.

Example 2: Restore an object by distinguished name

PS C:\> Restore-ADObject -Identity "CN=Kim Abercrombie\0ADEL:613dc90a-2afd-49fb-8bd8-eac48c6ab59f,CN=Deleted Objects,DC=FABRIKAM,DC=COM" -NewName "Kim Abercrombie" -TargetPath "OU=Finance,OU=UserAccounts,DC=FABRIKAM,DC=COM"

This command restores the ADObject while setting the msDS-LastKnownRDN attribute of the deleted object to NewName parameter and setting the lastKnownRDN to the TargetPath parameter.

Example 3: Restore an object from a filtered list of users

PS C:\> Get-ADObject -Filter 'samaccountname -eq "pattifuller"' -IncludeDeletedObjects | Restore-ADObject

This command finds a deleted user whose SAM account name is pattifuller and restores it.

Example 4: Restore an object by its GUID

PS C:\> Restore-ADObject -Identity '6bb3bfe9-4355-48ee-b3b6-4fda6917d31d' -Server server1:50000

This command restores an AD LDS object using ObjectGUID.

Example 5: Restore an object by its msds-LastKnownRDN attribute

PS C:\> Get-ADObject -Filter 'msds-lastknownrdn -eq "user1"' -Server server1:50000 -IncludeDeletedObjects -SearchBase "o=app1,c=us" | Restore-ADObject

This command restores an AD LDS object using the msds-LastKnownRDN attribute.

Required Parameters

-Identity

Specifies an Active Directory group object by providing one of the following values. The identifier in parentheses is the LDAP display name for the attribute. The acceptable values for this parameter are:

  • A distinguished name
  • A GUID (objectGUID)
  • A security identifier (objectSid)
  • A Security Account Manager account name (sAMAccountName)

The cmdlet searches the default naming context or partition to find the object. If two or more objects are found, the cmdlet returns a non-terminating error.

This parameter can also get this object through the pipeline or you can set this parameter to an object instance.

Type:ADObject
Position:0
Default value:None
Accept pipeline input:True (ByValue)
Accept wildcard characters:False

Optional Parameters

-AuthType

Specifies the authentication method to use. The acceptable values for this parameter are:

  • Negotiate or 0
  • Basic or 1

The default authentication method is Negotiate.

A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.

Type:ADAuthType
Parameter Sets:Negotiate, Basic
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Accept pipeline input:False
Accept wildcard characters:False
-Credential

Specifies the user account credentials to use to perform this task. The default credentials are the credentials of the currently logged on user unless the cmdlet is run from an Active Directory PowerShell provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the default.

To specify this parameter, you can type a user name, such as User1 or Domain01\User01 or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the Credential parameter to the PSCredential object.

If the acting credentials do not have directory-level permission to perform the task, Active Directory module for Windows PowerShell returns a terminating error.

Type:PSCredential
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-NewName

Specifies the new name of the object. This parameter sets the Name property of the Active Directory object. The LDAP display name (ldapDisplayName) of this property is name.

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Partition

Specifies the distinguished name of an Active Directory partition. The distinguished name must be one of the naming contexts on the current directory server. The cmdlet searches this partition to find the object defined by the Identity parameter.

In many cases, a default value is used for the Partition parameter if no value is specified. The rules for determining the default value are given below. Note that rules listed first are evaluated first and once a default value can be determined, no further rules are evaluated.

In Active Directory Domain Services (AD DS) environments, a default value for Partition is set in the following cases:

  • If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
  • If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
  • If none of the previous cases apply, the default value of Partition is set to the default partition or naming context of the target domain.

In Active Directory Lightweight Directory Services (AD LDS) environments, a default value for Partition is set in the following cases:

  • If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
  • If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
  • If the target AD LDS instance has a default naming context, the default value of Partition is set to the default naming context. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent object (nTDSDSA) for the AD LDS instance.
  • If none of the previous cases apply, the Partition parameter does not take a default value.
Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-Server

Specifies the AD DS instance to connect to, by providing one of the following values for a corresponding domain name or directory server. The service may be any of the following: AD LDS, AD DS, or Active Directory snapshot instance.

Specify the AD DS instance in one of the following ways:

Domain name values:

  • Fully qualified domain name
  • NetBIOS name

Directory server values:

  • Fully qualified directory server name
  • NetBIOS name
  • Fully qualified directory server name and port

The default value for this parameter is determined by one of the following methods in the order that they are listed:

  • By using the Server value from objects passed through the pipeline
  • By using the server information associated with the AD DS Windows PowerShell provider drive, when the cmdlet runs in that drive
  • By using the domain of the computer running Windows PowerShell
Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
-TargetPath

Specifies the new location for the object. This location must be the path to a container or organizational unit.

Type:String
