-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
-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
-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.
-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
-Confirm- Prompts you for confirmation before running the cmdlet.
-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.
-Identity (required)- 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.
-Instance (required)- 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.
-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.
-ManagedBy- Specifies the user or group that manages the object by providing one of the following property values. Note: The identifier in parentheses is the LDAP display name for the property. The acceptable values for this parameter are: - A distinguished name - A GUID (objectGUID) - A security identifier (objectSid) - A SAM account name (sAMAccountName) This parameter sets the Active Directory attribute with an LDAP display name of managedBy.
-PassThru- Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-PublicKeyRequiredPasswordRolling- Specifies whether the domain enables password expiration and rolling for user account that require a smart card for interactive sign in.
-Remove- Specifies that the cmdlet remove values of an object property. Use this parameter to remove one or more values of a property that cannot be modified using a cmdlet parameter. To remove an object property, you must use the LDAP display name. You can remove more than one property by specifying a semicolon-separated list. The format for this parameter is: -Remove @{Attribute1LDAPDisplayName=value[]; Attribute2LDAPDisplayName=value[]} When you use the *Add*, *Replace*, *Clear*, and *Remove* parameters together, the operations will be performed in the following order: - Remove - Add - Replace - Clear
-Replace- Specifies values for an object property that will replace the current values. Use this parameter to replace 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 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: -Replace @{Attribute1LDAPDisplayName=value1, value2, ...; Attribute2LDAPDisplayName=value1, value2, ...; AttributeNLDAPDisplayName=value1, value2, ...} When you use the *Add*, *Remove*, *Replace*, and *Clear* parameters together, the operations will be performed in the following order: - Remove - Add - Replace - Clear
-Server- Specifies the Active Directory Domain Services 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: Active Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory snapshot instance. Specify the Active Directory Domain Services 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 Active Directory Domain Services Windows PowerShell provider drive, when the cmdlet runs in that drive - By using the domain of the computer running Windows PowerShell
-WhatIf- Shows what would happen if the cmdlet runs. The cmdlet is not run.
