Parameters

-AccountName: Specifies an array of names of the trustees. Use a comma-separated list to specify multiple trustees.
-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-CimSession: Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-Confirm: Prompts you for confirmation before running the cmdlet.
-Force: Forces the command to run without asking for user confirmation.
-InputObject (required): Specifies the input object that is used in a pipeline command.
-Name (required): Specifies an array of names of the SMB shares.
-ScopeName: Specifies an array of names of the scopes.
-SmbInstance: Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.
-ThrottleLimit: Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-WhatIf: Shows what would happen if the cmdlet runs. The cmdlet is not run.

Prerequisites

Security considerations

This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
