Description

The Set-ADDomain cmdlet modifies the properties of an Active Directory domain. You can modify commonly used property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be modified by using the Add, Replace, Clear, and Remove parameters.

The Identity parameter specifies the domain to modify. You can identify a domain by its distinguished name, GUID, security identifier (SID), DNS domain name, or NetBIOS name. You can also set the Identity parameter to an object variable such as $<localDomainObject>, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-ADDomain cmdlet to retrieve a domain object and then pass the object through the pipeline to the Set-ADDomain cmdlet.

The Instance parameter provides a way to update a domain object by applying the changes made to a copy of the domain object. When you set the Instance parameter to a copy of an Active Directory domain object that has been modified, the Set-ADDomain cmdlet makes the same changes to the original domain object. To get a copy of the object to modify, use the Get-ADDomain object. When you specify the Instance parameter you should not pass the Identity parameter. For more information about the Instance parameter, see the Instance parameter description.

Examples

Example 1: Set the value of a property in a domain

PS C:\> Set-ADDomain -Identity USER01 -AllowedDNSSuffixes @{Replace="USER01.com","corp.USER01.com"}

This command sets the value of AllowedDNSSuffixes to {"USER01.com","corp.USER01.com"} in domain USER01.

Example 2: Set the value of a property in a domain

PS C:\> Set-ADDomain -Identity USER01 -AllowedDNSSuffixes @{Add="corp.USER01.com"}

This command adds the value corp.USER01.com to the AllowedDNSSuffixes in domain USER01.

Example 3: Set the ManagedBy property in a domain

PS C:\> Set-ADDomain -Identity USER01 -ManagedBy 'CN=Domain Admins,CN=Users,DC=USER01,DC=COM'

This command sets the ManagedBy property in domain USER01 to CN=Domain Admins,CN=Users,DC=USER01,DC=COM.

Example 4: Set the time in days for replication for the current logged on user

PS C:\> Get-ADDomain | Set-ADDomain -LastLogonReplicationInterval "10"

This command sets the LastLogonReplicationInterval of the current logged on user domain to 10.

Example 5: Set the ManagedBy property for a domain

PS C:\> $Domain = Get-ADDomain -Identity London
PS C:\> $Domain.ManagedBy = PattiFuller
PS C:\> Set-ADDomain -Instance $Domain

This command modifies the ManagedBy property for the London domain. The example modifies a local instance of the London domain, and then specifies the Instance parameter for the current cmdlet as the local instance.

Example 6: Enable password expiration and rolling for public key to sign in

PS C:\> Set-ADDomain -Identity FABRIKAM -PublicKeyRequiredPasswordRolling $True

This command sets the msDS-ExpirePasswordsOnSmartCardOnlyAccounts attribute for the FABRIKAM domain to $True. This setting enables password expiration and rolling for user accounts that require a public key to sign in.

Parameters

-Add

Specifies values to add to an object property. Use this parameter to add one or more values to a property that cannot be modified using a cmdlet parameter. To modify an object property, you must use the Lightweight Directory Access Protocol (LDAP) display name. You can specify multiple values to a property by specifying a comma-separated list of values and more than one property by separating them using a semicolon. The format for this parameter is

-Add @{Attribute1LDAPDisplayName=value1, value2, ...; Attribute2LDAPDisplayName=value1, value2, ...; AttributeNLDAPDisplayName=value1, value2, ...}

When you use the Add, Replace, Clear, and Remove parameters together, the operations are performed in the following order:

• Remove
• Add
• Replace
• Clear

Type:	Hashtable
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-AllowedDNSSuffixes

Modifies the list of domain name server (DNS) suffixes that are allowed in a domain. This parameter sets the value of the msDS-AllowedDNSSuffixes attribute of the domainDNS object. This parameter uses the following syntax to add, remove, replace, or clear DNS suffix values.

To add values:

-AllowedDNSSuffixes @{Add=value1,value2,...}

To remove values:

``-AllowedDNSSuffixes @{Remove=value3,value4,...}

To replace values:

-AllowedDNSSuffixes @{Replace=value1,value2,...}

To clear all values:

-AllowedDNSSuffixes $Null

You can specify more than one change by using a list separated by semicolons. For example, use the following syntax to add and remove DNS suffix values:

@{Add=value1,value2,...};@{Remove=value3,value4,...}

When you use the Add, Replace, Clear, and Remove parameters together, the operations are performed in the following order:

• Remove
• Add
• Replace
• Clear

Type:	Hashtable
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-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
Accepted values:	Negotiate, Basic
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Clear

Specifies an array of object properties that are cleared in the directory. Use this parameter to clear one or more values of a property that cannot be modified using a cmdlet parameter. To modify an object property, you must use the LDAP display name. You can modify more than one property by specifying a comma-separated list. The format for this parameter is:

-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName

When you use the Add, Replace, Clear, and Remove parameters together, the operations are performed in the following order:

• Remove
• Add
• Replace
• Clear

Type:	String[]
Position:	Named
Default value:	None
Required:	False
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
Required:	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 module for Windows 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
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Identity

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

• A distinguished name
• A GUID (objectGUID)
• A security identifier (objectSid)
• A DNS domain name
• A NetBIOS domain name

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 a domain object instance.

Type:	ADDomain
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Instance

Specifies a modified copy of a domain object to use to update the actual Active Directory domain object. When this parameter is used, any modifications made to the modified copy of the object are also made to the corresponding Active Directory object. The cmdlet only updates the object properties that have changed.

The Instance parameter can only update domain objects that have been retrieved by using the Get-ADDomain cmdlet. When you specify the Instance parameter, you cannot specify other parameters that set properties on the object.

Type:	ADDomain
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-LastLogonReplicationInterval

Specifies the time, in days, within which the last logon time of an account must be replicated across all domain controllers in the domain. This parameter sets the LastLogonReplicationInterval property for a domain. The LDAP display name (ldapDisplayName) for this property is msDS-LogonTimeSyncInterval. The last logon replication interval must be at least one day. Setting the last logon replication interval to a low value can significantly increase domain-wide replication.

Type:	TimeSpan
Position:	Named
