In the NTFS file system, the person ultimately responsible for the permissions assigned to a file, usually the creator of a file. By default, the owner of a file has permission to modify the object’s discretionary access control list (DACL) by granting users and groups permissions for various objects.
A file always has an owner. Ownership creates a trail of accountability for the file. The ownership of a file on an NTFS volume can be changed in two ways:
In the Microsoft Windows 2000 operating system, objects in Active Directory also have owners. The user who creates an object in Active Directory becomes the object’s owner. The owner controls the permissions for the object and its attributes. Ownership of an object in Active Directory can be changed in ways similar to those for a file on an NTFS volume.
