Synopsis
Description
The Identity parameter specifies the domain controller to get. You can identify a domain controller by its GUID, IPV4Address, global IPV6Address, or DNS host name. You can also identify a domain controller by the name of the server object that represents the domain controller, the Distinguished Name (DN) of the NTDS settings object or the server object, the GUID of the NTDS settings object or the server object under the configuration partition, or the DN of the computer object that represents the domain controller. You can also set the Identity parameter to a domain controller object variable, such as $, or pass a domain controller object through the pipeline to the Identity parameter.
To search for and retrieve more than one domain controller, use the Filter parameter. The Filter parameter uses the PowerShell Expression Language to write query strings for Active Directory. PowerShell Expression Language syntax provides rich type conversion support for value types received by the Filter parameter. For more information about the Filter parameter syntax, see about_ActiveDirectory_Filter. You cannot use an LDAP query string with this cmdlet.
To get a domain controller by using the discovery mechanism of DCLocator, use the Discover parameter. You can provide search criteria by setting parameters such as Service, SiteName, DomainName, NextClosestSite, AvoidSelf, and ForceDiscover.
Parameters
-AuthType
Specifies the authentication method to use. Possible values for this parameter include:
Required? false
Position? named
Default value Microsoft.ActiveDirectory.Management.AuthType.Negotiate
Accept pipeline input? false
Accept wildcard characters? false
-AvoidSelf <SwitchParameter>
Specifies to not return the current computer as a domain controller. If the current computer is not a domain controller, this parameter is ignored. You can specify this parameter when you want to get the name of another domain controller in the domain.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-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.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Discover <SwitchParameter>
Specifies to return a discoverable domain controller that meets the conditions specified by the cmdlet parameters.
Required? true
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-DomainName <String>
Specifies the domain to search. The cmdlet locates a discoverable domain controller in this domain. Specify the domain by using the NetBIOS name or Fully Qualified Domain Name (FQDN) of the domain.
Required? false
Position? named
Default value Name of the domain to which this machine is joined
Accept pipeline input? false
Accept wildcard characters? false
-Filter <String>
Specifies a query string that retrieves Active Directory objects. This string uses the PowerShell Expression Language syntax. The PowerShell Expression Language syntax provides rich type-conversion support for value types received by the Filter parameter. The syntax uses an in-order representation, which means that the operator is placed between the operand and the value. For more information about the Filter parameter, see about_ActiveDirectory_Filter.
Required? true
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-ForceDiscover <SwitchParameter>
Forces the cmdlet to clear any cached domain controller information and perform a new discovery. If this parameter is not specified the cmdlet may return cached domain controller information.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Identity <ADDomainController>
Specifies an Active Directory domain controller object by providing one of the following values. The identifier in parentheses is the LDAP display name for the attribute. Unless specified otherwise, these values are for the server object that represents the domain controller.
Required? false
Position? 1
Default value
Accept pipeline input? True (ByValue)
Accept wildcard characters? false
-MinimumDirectoryServiceVersion <ADMinimumDirectoryServiceVersion>
Species the earliest operating system that the domain controller can have so that it is returned by the cmdlet when getting a DC using -Discover switch. Possible values are:
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-NextClosestSite <SwitchParameter>
Specifies to return a domain controller in the next closest site when a domain controller is not found in the site that contains the client. The next closest site is the site with the lowest site link cost with respect to the current site. Costs between sites are based on factors such as bandwidth, as well as physical proximity.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-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.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-Service <ADDiscoverableService[]>
Species the types of domain controllers to get. You can specify more than one type by using a comma-separated list. Possible values for this parameter are:
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false
-SiteName <String>
Specifies the name of a site to search in to find the domain controller. If this parameter is not set, the cmdlet searches for domain controllers in the same site as the client. The name of the site is defined by the Name property of the site object.
Required? false
Position? named
Default value Name of the site that the client is in
Accept pipeline input? false
Accept wildcard characters? false
-Writable <SwitchParameter>
Specifies whether or not this is a writable domain controller.
Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? falseSyntax
