Windows Server 2012 R2 and Windows 8.1

Updated: July 8, 2014

Applies To: Windows 8.1, Windows PowerShell 4.0, Windows Server 2012 R2

Set-ADDomainMode

Sets the domain mode for an Active Directory domain.

Syntax

Parameter Set: Default
Set-ADDomainMode [-Identity] <ADDomain> [-DomainMode] <ADDomainMode> {UnknownDomain | Windows2000Domain | Windows2003InterimDomain | Windows2003Domain | Windows2008Domain | Windows2008R2Domain | Windows2012Domain | Windows2012R2Domain} [-AuthType <ADAuthType> {Negotiate | Basic} ] [-Credential <PSCredential> ] [-PassThru] [-Server <String> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Set-ADDomainMode cmdlet sets the domain mode for a domain. You specify the domain mode by setting the DomainMode parameter.

The Identity parameter specifies the Active Directory domain to modify. You can identify a domain by its distinguished name (DN), GUID, security identifier (SID), DNS domain name, or NetBIOS name. You can also set the Identity parameter to a domain object variable such as $<localADDomainObject>, or you can pass a domain 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 operator to the Set-ADDomainMode cmdlet.

The Set-ADDomainMode cmdlet always prompts for permission unless you specify -confirm:$false.

Parameters

-AuthType<ADAuthType>

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.

-Credential<PSCredential>

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 PowerShell returns a terminating error.

-DomainMode<ADDomainMode>

Specifies the domain functional level of the first domain in the creation of a new forest. Supported values for this parameter can be either a valid integer or a corresponding enumerated string value. For example, to set the domain mode level to Windows Server 2008 R2, you can specify either a value of 4 or Win2008R2Domain.

The following are the currently supported values:

     -- Windows Server 2003: 2 or Win2003Domain
     -- Windows Server 2008: 3 or Win2008Domain
     -- Windows Server 2008 R2: 4 or Win2008R2Domain
     -- Windows Server 2012: 5 or Win2012Domain
     -- Windows Server 2012 R2: 6 or Win2012R2Domain

The domain functional level cannot be lower than the forest functional level, but it can be higher. The default is automatically computed and set.

-Identity<ADDomain>

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.

-Server<String>

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 ServicesWindows PowerShell provider drive, when the cmdlet runs in that drive
-- By using the domain of the computer running Windows PowerShell

Examples

-------------------------- EXAMPLE 1 --------------------------

This command sets the DomainMode property of the fabrikam.com domain to Windows2003Domain.


PS C:\> Set-ADDomainMode -Identity fabrikam.com -DomainMode Windows2003Domain

-------------------------- EXAMPLE 2 --------------------------

This example sets the DomainMode of the current logged on user's domain to Windows2003Domain. The set operation targets the PrimaryDC FSMO to apply the update.


PS C:\> $pdc = Get-ADDomainController -Discover -Service PrimaryDC
PS C:\> Set-ADDomainMode -Identity $pdc.Domain -Server $pdc.HostName[0] -DomainMode Windows2003Domain
