You need to quickly ensure that the application can run

A company has an Active Directory Domain Services (AD DS) domain. All client computers
run Windows 8 and are joined to the domain. All Sales department employees are members
of the Sales organizational unit (CU). AppLocker rules control the installation of applicatior
on client computers.
You create a new Group Policy object (GPO) to configure an AppLocker file hash rule. The
file hash rule allows an application to run and links the application to the Sales OU. Several
minutes later, you establish that the AppLocker rule is not present on some computers within
SalesOU and the application cannot run.
