New-ADServiceAccount is accessible with the help of addsadministration module. To install addsadministration on your system please refer to this link.

Synopsis

Creates a new Active Directory managed service account or group managed service account object.

Description

The New-ADServiceAccount cmdlet creates a new Active Directory managed service account (MSA). By default a group MSA is created. To create a standalone MSA which is linked to a specific computer, the -Standalone parameter is used. To create a group MSA which can only be used in client roles, the -Agent parameter is used. This creates a group MSA which can be used for outbound connections only and attempts to connect to services using this account will fail since the account does not have enough information for authentication to be successful. You can set commonly used MSA property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be set by using the OtherAttributes parameter.

The Path parameter specifies the container or organizational unit (OU) for the new MSA object. When you do not specify the Path parameter, the cmdlet creates an object in the default Managed Service Accounts container for MSA objects in the domain.

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

Method 1: Use the New-ADServiceAccount 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 MSA object or retrieve a copy of an existing MSA 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. For examples and more information, see the Instance parameter description for this cmdlet.

Method 3: Use the Import-CSV cmdlet with the New-ADServiceAccount cmdlet to create multiple Active Directory MSA 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 through the pipeline to the New-ADServiceAccount cmdlet to create the MSA objects.

Parameters 

-AccountExpirationDate 
         Specifies the expiration date for an account. When you set this parameter to 0, the account never expires. This parameter sets the AccountExpirationDate property of an account object. The LDAP Display name (ldapDisplayName) for this property is accountExpires.
