Explanation:
When User1 connects to \https://www.google.com/search?q=Server1.adatum.com\Share1, the user can take ownership of File1.txt.: Yes When User2 connects to \https://www.google.com/search?q=Server1.adatum.com\Share1, File1.txt is visible.: Yes When User3 connects to \https://www.google.com/search?q=Server1.adatum.com\Share1, File1.txt is visible.: No In Windows Server Hybrid environments, access to files over a network is governed by the intersection of Share Permissions, NTFS (File) Permissions, and Access-Based Enumeration (ABE).
* Ownership Rights: User1 has Full Control in the NTFS permissions for File1.txt. In Windows security, the Full Control right inherently includes the "Take Ownership" and "Change Permissions" rights. While the Share permission for "Domain Users" is set to Change, which normally restricts permission changes over the wire, a user with NTFS Full Control can still perform ownership operations if they have sufficient effective rights. Therefore, User1 can take ownership.
* File Visibility and ABE: The exhibit for Share1 shows that FolderEnumerationMode is set to AccessBased. Access-Based Enumeration (ABE) ensures that users only see the files and folders for which they have at least Read (or equivalent) NTFS permissions.
* User2: The NTFS permissions grant User2 Read access to File1.txt. Since User2 has read access, ABE will allow the file to be visible when the user browses the share.
* User3: The NTFS permissions grant User3 Write access but not Read access. ABE specifically requires the "Read" permission for a file to be visible in a directory listing. Because User3 lacks the Read permission, File1.txt will be hidden from their view, even though they have Write rights to the underlying file.
