title: Exception calling "SetAccessRule" with "1" argument(s) ::: Powershell Error
body: <p>I get an error with my Powershell script where I am trying to give a folder "Total Control". I can give Total Control to a Domain/Users account, but I can't seem to get it to work for a ComputerName\Users account. This is important to allow other software being installed to work on various computers in our organization (they all have a ComputerName\Users account in the Security tab). I want to give Total Control to [ComputerName\Users] account.</p>
  
  <p>Screenprint below shows DomainUsers/Account my script could create, and below it the ComputerName\Account I can't reference in any way to give Total Control -- In this example, "Users(OHAIBMG00B7KP\Users)", triggers an error.</p>

  <p>This script works to create Account and Total Control permissions for a folder</p>
  
  <pre><code>$directory = "C:\Program Files (x86)\CAREWare"
  $domainName = "DHS"
  $group = 'Domain Users'
  $inherit = [system.security.accesscontrol.InheritanceFlags]"ContainerInherit, ObjectInherit"
  $propagation = [system.security.accesscontrol.PropagationFlags]"None"
  $acl = (Get-Item $directory).GetAccessControl("Access")
  $user = "{0}\{1}" -f "$domainName", $group
  $user.trim()
  $access = "FullControl"
  $accessType = "Allow"
  $accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule -ArgumentList @("$user","$access", "$inherit", "$propagation", "$accessType")
  $acl.SetAccessRule($accessRule)
  set-acl $directory $acl
  </code></pre>
  
  <p>This is the error when I try to change the three lines below to reference ComputerName\Users.</p>
  
  <pre><code>$directory = "C:\Program Files (x86)\CAREWare"
  $domainName = $env:computername
  $group = 'Users'
  
  Exception calling "SetAccessRule" with "1" argument(s): "Some or all identity references could not be translated."

  <p>I can't seem to get PowerShell to find and return anything about the ComputerName\Users group, but it is there in the Security Tab of the Folder Properties.</p>
