Final answer:
The question pertains to configuring network file server access to allow only a specific group of users (Matthews) to access files within a folder named 'BalkFiles' on a server named 'Bowman'.
Step-by-step explanation:
The answer to the question is related to network file sharing and access control configuration. The administration work involves setting up permissions so that only the Matthews group can access the 'BalkFiles' folder on the network file server named Bowman. To achieve this, the administrator must modify the folder's access control list (ACL) to grant exclusive access rights to the Matthews group, while denying or not granting access rights to other users or groups.
