Global groups can only contain users, not local groups or other global groups. This is a complex aspect of Windows NT, and a source of much confusion. Groups are covered in greater depth in the topic entitled Accounts and Policies . Profiles Profiles in Windows NT are essentially a set of files that specifically configure a Windows NT or Windows 9x client when the user logs in. Windows NT profiles include registry settings covering desktop appearance and application settings, as well the contents of the desktop and the start menu.
Profiles can be local to a specific computer, or they can follow the user wherever they log in.
Shares A share is created when the user decides to share a directory over the network. Any Windows NT computer can share files and printers, as can Windows 9x computers when file and printer sharing are enabled. When browsing the Network Neighborhood, a user who double clicks on a computer name will then see a list of the shares that that computer offers. User-created shares have their own set of permissions, but Windows NT can automatically create default hidden shares that are needed for administrative purposes and cannot be altered. Share-level permissions and the permissions applied to an NTFS directory within that share are independent and can interact with confusing results.
