Local Password and host file

I have created a GP in Computer configuration to update the local administrator password and copy a version of host file to all machines under a OU.

Both these settings are not working on client machine.

For password - Under computer configuration -> control panel settings -> local users and groups -> Admin -> update password

For Host -> computer configuration -> Windows settings -> files -> source path - unc path for my share folder which has the host file & TArget path : c:\windows\sytem32\drivers\etc and given action as replace.

what's wrong iam doing in this?
