Description

The New-ADComputer cmdlet creates a new Active Directory computer object. This cmdlet does not join a computer to a domain. You can set commonly used computer property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be modified by using the OtherAttributes parameter.

You can use this cmdlet to provision a computer account before the computer is added to the domain. These pre-created computer objects can be used with offline domain join, unsecure domain join, and RODC domain join scenarios.

The Path parameter specifies the container or organizational unit (OU) for the new computer. When you do not specify the Path parameter, the cmdlet creates a computer account in the default container for computer objects in the domain.

The following methods explain different ways to create an object by using this cmdlet.

Method 1: Use the New-ADComputer cmdlet, specify the required parameters, and set any additional property values by using the cmdlet parameters.

Method 2: Use a template to create the new object. To do this, create a new computer object or retrieve a copy of an existing computer object and set the Instance parameter to this object. The object provided to the Instance parameter is used as a template for the new object. You can override property values from the template by setting cmdlet parameters.

Method 3: Use the Import-Csv cmdlet with the Add-ADComputerServiceAccount cmdlet to create multiple Active Directory computer objects. To do this, use the Import-Csv cmdlet to create the custom objects from a comma-separated value (CSV) file that contains a list of object properties. Then pass these objects to the New-ADComputer cmdlet by using the pipeline operator to create the computer objects.

Examples

Example 1: Create a new computer account in an organization unit

PS C:\> New-ADComputer -Name "USER02-SRV2" -SamAccountName "USER02-SRV2" -Path "OU=ApplicationServers,OU=ComputerAccounts,OU=Managed,DC=USER02,DC=COM"

This command creates a new computer account in the OU OU=ApplicationServers,OU=ComputerAccounts,OU=Managed,DC=USER02,DC=COM.

Example 2: Create a new computer account under an organization unit in a specified region

PS C:\> New-ADComputer -Name "USER01-SRV3" -SamAccountName "USER01-SRV3" -Path "OU=ApplicationServers,OU=ComputerAccounts,OU=Managed,DC=USER01,DC=COM" -Enabled $True -Location "Redmond,WA"

This command creates a new computer account under a particular OU, which is enabled and located in Redmond, WA.

Example 3: Create a new computer account from a template

PS C:\> $TemplateComp = Get-ADComputer -Name "LabServer-00" -Properties "Location","OperatingSystem","OperatingSystemHotfix","OperatingSystemServicePack","OperatingSystemVersion" 
PS C:\> New-ADComputer -Instance $TemplateComp -Name "LabServer-01"

This example creates a new computer account from a template object.

Parameters

-AccountExpirationDate

Specifies the expiration date for an account. This parameter sets the AccountExpirationDate property of an account object. The Lightweight Directory Access Protocol (LDAP) display name (ldapDisplayName) for this property is accountExpires.

Use the DateTime syntax when you specify this parameter. Time is assumed to be local time unless otherwise specified. When a time value is not specified, the time is assumed to 12:00:00 AM local time. When a date is not specified, the date is assumed to be the current date.

Type:DateTime
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-AccountNotDelegated

Specifies whether the security context of the user is delegated to a service. When this parameter is set to true, the security context of the account is not delegated to a service even when the service account is set as trusted for Kerberos delegation. This parameter sets the AccountNotDelegated property for an Active Directory account. This parameter also sets the ADS_UF_NOT_DELEGATED flag of the Active Directory User Account Control (UAC) attribute. The acceptable values for this parameter are:

  • $False or 0
  • $True or 1
Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-AccountPassword

Specifies a new password value for an account. This value is stored as an encrypted string.

The following conditions apply based on the manner in which the password parameter is used:

  • $Null password is specified: random password is set and the account is enabled unless it is requested to be disabled.
  • No password is specified: random password is set and the account is enabled unless it is requested to be disabled.
  • User password is specified: password is set and the account is enabled unless it is requested to be disabled, unless the password you provided does not meet password policy or was not set for other reasons, at which point the account is disabled.

Notes: Computer accounts, by default, are created with a 240-character random password. If you provide a password, an attempt is made to set that password. However, this can fail due to password policy restrictions. The computer account is created and you can use Set-ADAccountPassword to set the password on that account. In order to ensure that accounts remain secure, computer accounts will never be enabled unless a valid password is set (either a randomly-generated or user-provided one) or PasswordNotRequired is set to $True.

The account is created if the password fails for any reason.

The new ADComputer object will always either be disabled or have a user-requested or randomly-generated password. There is no way to create an enabled computer account object with a password that violates domain password policy, such as an empty password.

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.

-Path

Specifies the X.500 path of the Organizational Unit (OU) or container where the new object is created.

In many cases, a default value is used for the Path parameter if no value is specified. The rules for determining the default value are given below. Note that rules listed first are evaluated first and once a default value can be determined, no further rules are evaluated.

In Active Directory Domain Services environments, a default value for Path is set in the following cases:

  • If the cmdlet is run from an Active Directory module for Windows PowerShell provider drive, the parameter is set to the current path of the provider drive.
  • If the cmdlet has a default path, this value is used. For example: in New-ADUser, the Path parameter would default to the Users container.
  • If none of the previous cases apply, the default value of Path is set to the default partition or naming context of the target domain.

In Active Directory Lightweight Directory Services (AD LDS) environments, a default value for Path is set in the following cases:

  • If the cmdlet is run from an Active Directory module for Windows PowerShell provider drive, the parameter is set to the current path of the provider drive.
  • If the cmdlet has a default path, this value is used. For example: in New-ADUser, the Path parameter would default to the Users container.
  • If the target AD LDS instance has a default naming context, the default value of Path is set to the default naming context. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent (DSA) object (nTDSDSA) for the AD LDS instance.
  • If none of the previous cases apply, the Path parameter will not take any default value.

Note: The Active Directory Provider cmdlets, such as New-Item, Remove-Item, Remove-ItemProperty, Rename-Item, and Set-ItemProperty, also contain a Path property. However, for the provider cmdlets, the Path parameter identifies the path of the actual object and not the container as with the Active Directory cmdlets.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-PrincipalsAllowedToDelegateToAccount

Accept pipeline input:True
Accept wildcard characters:False

-SAMAccountName

Specifies the Security Account Manager (SAM) account name of the user, group, computer, or service account. The maximum length of the description is 256 characters. To be compatible with older operating systems, create a SAM account name that is 15 characters or less. This parameter sets the SAMAccountName for an account object. The LDAP display name (ldapDisplayName) for this property is sAMAccountName.

Note: If the SAMAccountName string provided does not end with a $, a $ will be appended if needed.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-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
Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ServicePrincipalNames

Specifies the service principal names for the account. This parameter sets the ServicePrincipalNames property of the account.

Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-UserPrincipalName

Specifies a user principal name (UPN) in the format <user>@<DNS-domain-name>. A UPN is a friendly name assigned by an administrator that is shorter than the LDAP distinguished name used by the system and easier to remember. The UPN is independent of the user object's distinguished name, so a user object can be moved or renamed without affecting the user logon name. When logging on using a UPN, users no longer have to choose a domain from a list on the logon dialog box.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False
