Updated: July 8, 2014

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

Get-ADDomain

Gets an Active Directory domain.

Syntax

Parameter Set: Current
Get-ADDomain [-AuthType <ADAuthType> {Negotiate | Basic} ] [-Credential <PSCredential> ] [-Current <ADCurrentDomainType> {LocalComputer | LoggedOnUser} ] [-Server <String> ] [ <CommonParameters>]

Parameter Set: Identity
Get-ADDomain [-Identity] <ADDomain> [-AuthType <ADAuthType> {Negotiate | Basic} ] [-Credential <PSCredential> ] [-Server <String> ] [ <CommonParameters>]




Detailed Description

The Get-ADDomain cmdlet gets the Active Directory domain specified by the parameters. You can specify the domain by setting the Identity or Current parameters.

The Identity parameter specifies the Active Directory domain to get. You can identify the domain object to get by its Distinguished Name (DN), GUID, Security Identifier (SID), DNS domain name, or NetBIOS name. You can also set the parameter to a domain object variable, such as $<localDomainObject> or pass a domain object through the pipeline to the Identity parameter.

To get the domain of the local computer or current logged on user (CLU) set the Current parameter to LocalComputer or LoggedOnUser. When you set the Current parameter, you do not need to set the Identity parameter.

When the Current parameter is set to LocalComputer or LoggedOnUser, the cmdlet uses the Server and Credential parameters according to the following rules.

- If both the Server and Credential parameters are not specified:

-- The domain is set to the domain of the LocalComputer or LoggedOnUser and a server is located in this domain. The credentials of the current logged on user are used to get the domain.

- If the Server parameter is specified and the Credential parameter is not specified:

-- The domain is set to the domain of the specified server and the cmdlet checks to make sure that the server is in the domain of the LocalComputer or LoggedOnUser. Then the credentials of the current logged on user are used to get the domain. An error is returned when the server is not in the domain of the LocalComputer or LoggedOnUser.

- If the Server parameter is not specified and the Credential parameter is specified:

-- The domain is set to the domain of the LocalComputer or LoggedOnUser and a server is located in this domain. Then the credentials specified by the Credential parameter are used to get the domain.

- If the Server and Credential parameters are specified:

-- The domain is set to the domain of the specified server and the cmdlet checks to make sure that the server is in the domain of the LocalComputer or LoggedOnUser. Then the credentials specified by the Credential parameter are used to get the domain. An error is returned when the server is not in the domain of the LocalComputer or LoggedOnUser.

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.

-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
