The Administrator can go so far, for example, as to restrict individual files to individual users, although more typically, as with FTP access or restricted Web or intranet access, a folder and its subfolders are given permissions that apply to an entire group of users. The Administrator group, for example, has full control over all files on the system, while other user groups can be given other permissions. Windows NT has several permission types. Read , Write , Execute , and Delete are all straightforward. Change allows reading plus changing file attributes and displaying permissions.
List lets a user view a directory.
Full Access eliminates all restrictions, and No Access is self-explanatory. Permissions for a file or folder are set by means of the Properties dialog, which is accessible through My Computer or the Windows NT Explorer. User rights in Windows NT can get complicated. User or group rights on a specific workstation apply only to that particular workstation, but rights on servers extend across a Windows NT domain system. Rights include such activities as accessing the computer from the network, backing up folders and files, logging on to a local workstation, shutting down the system, loading and unloading device drivers, logging on as a system service, updating the system time and date, and taking ownership of files, folders, or other items, such as printers.
