Add the administrative template to Active Directory

1. On a domain controller or workstation with RSAT, go to the PolicyDefinition folder (also known as the Central Store) on any domain controller for your domain.
2. Copy the "WAU.admx" file to the PolicyDefinition folder. (Example: %systemroot%\sysvol\domain\policies\PolicyDefinitions)
3. Copy the "WAU.adml" file to the matching language folder in the PolicyDefinition folder. Create the folder if it doesn't already exist. (Example: %systemroot%\sysvol\domain\policies\PolicyDefinitions\EN-US)
4. If your domain has more than one domain controller, the new ADMX files will be replicated to them at the next domain replication interval.
