Hot to get shared folders permissions with a powershell script

with this powershell script we’ll be able to get share permissions and ntfs permissions form all the shares of our servers list.

Function GetSharedFolderPermission($ComputerName)
{
	#test server connectivity
	$PingResult = Test-Connection -ComputerName $ComputerName -Count 1 -Quiet
	if($PingResult)
