You are the administrator of Ezonexam's Windows 2000 network. You need to store secured files for Ezonexam's accounting and legal departments on a Windows 2000 Professional computer. You create two shared folders named Accounting and Legal with the default NTFS and share permissions. You also create two groups named Accounting and Legal and add the appropriate user accounts into the appropriate groups. To meet the security requirements for the shared folders the following criteria must be met: 1. Users in both departments must be able to update their own files from the network. 2. Users in the accounting department must be able to view the legal department's documents from the network. 3. Users in the legal department must be prevented from being able to view the accounting department's documents from the network. You want to ensure that all security requirements are met using the least amount of administrative effort. What should you do?
