You are correct. This seems to be a subtle misinterpretation of the instructions. Only an administrative user can grant or deny permissions to a non-administrative account. As such, you would need to login to the server as the Administrator to grant the user permissions to these services. It would likely make more sense written as it is below. Bronx will update this KB article accordingly to avoid any potential confusion. Nice catch tonyled!
