By default, NTFS folder permission inheritance is enabled. But in some cases, the administrator needs to disable it. If you have a lot of folders with folder permission inheritance disabled, you can use the following PowerShell script to enable it.
Use this code to enable folder permission inheritance on a folder and all the subfolders.
$allFolders=Get-ChildItem -Path C:\MySource -Directory -Recurse
foreach ($Folder in $allFolders){
$Permission=get-acl -Path $Folder.FullName
$Permission.SetAccessRuleProtection($False,$true)
Set-Acl -Path $Folder.FullName -AclObject $Permission
}You can refer to Microsoft Site to know the argument assigned with SetAccessRuleProtection
