Set-ADDomainMode

Set-ADDomainMode

Sets the domain mode for an Active Directory domain.

Syntax

Set-ADDomainMode [-Identity] <ADDomain> [-DomainMode] {<Windows2000Domain> | <Windows2003InterimDomain> | <Windows2003Domain> | <Windows2008Domain> | <Windows2008R2Domain> | <UnknownDomain>} [-AuthType {<Negotiate> | <Basic>}] [-Credential <PSCredential>] [-PassThru <switch>] [-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 domain mode can be set to the following values that are listed in order of functionality from lowest to highest.
Windows2000Domain
Windows2003InterimDomain
Windows2003Domain
Windows2008Domain
Windows2008R2Domain
You can change the domain mode to a mode with higher functionality only. For example, if the domain mode for a domain is set to Windows 2003, you can use this cmdlet to change the mode to Windows 2008. However, in the same situation, you cannot use this cmdlet to change the domain mode from Windows 2003 to Windows 2000.
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 $<localADDomainObject>, or you can pass a domain object through the pipeline to the Identity parameter. For example, you can use the Get-ADDomain cmdlet to retrieve a domain object and then pass the object through the pipeline to the Set-ADDomainMode cmdlet.
The Set-ADDomainMode always prompts for permission unless you specify -confirm:$false.

Parameters

AuthType

Specifies the authentication method to use. Possible values for this parameter include:
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.
The following example shows how to set this parameter to Basic.
-AuthType Basic

The following lists the acceptable values for this parameter:

· Negotiate

· Basic

Default Value: Microsoft.ActiveDirectory.Management.AuthType.Negotiate

Data Type: ADAuthType

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 "Domain01User01" 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 The following example shows how to create credentials.
$AdminCredentials = Get-Credential "Domain01User01"
The following shows how to set the Credential parameter to these credentials.
-Credential $AdminCredentials
If the acting credentials do not have directory-level permission to perform the task, Active Directory PowerShell returns a terminating error.

Default Value:

Data Type: PSCredential

DomainMode

Specifies the domain mode for an Active Directory domain. You can set the domain mode to one of the following values that are listed in order of functionality from least to most.
Windows2000Domain or 0
Windows2003InterimDomain or 1
Windows2003Domain or 2
Windows2008Domain or 3
Windows2008R2Domain or 4
The following example shows how to set this parameter to Windows 2008 R2.
-DomainMode Windows2008R2Domain

The following lists the acceptable values for this parameter:

· Windows2000Domain

· Windows2003InterimDomain

· Windows2003Domain

· Windows2008Domain

· Windows2008R2Domain

· UnknownDomain

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.
Distinguished Name
Example: DC=redmond,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-
DNS domain name
Example: redmond.corp.contoso.com
NetBIOS domain name
Example: redmond
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.
This example shows how to set the parameter to a distinguished name.
-Identity "DC=redmond,DC=corp,DC=contoso,DC=com"
This example shows how to set this parameter to a domain object instance named "domainInstance".
-Identity $domainInstance

Default Value:

Data Type: ADDomain

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.

-By using Server value from objects passed through the pipeline.
-By using the server information associated with the Active Directory PowerShell provider drive, when running under that drive.
-By using the domain of the computer running Powershell.
