9-14 Chapter 9 Administering Shared Folders
Table 9-5 Client Computer Operating Systems and Share Name Length
Operating System Share Name Length
Windows 2000 and later 80 characters
Windows NT, Windows 98, and Windows 95 12 characters
MS-DOS, Windows 3.x, and Windows for Workgroups 8.3 characters
Windows XP Professional provides 8.3-character equivalent names, but the resulting
names might not be intuitive to users. For example, a Windows XP Professional folder
named Accountants Database would appear as Accoun~1 on client computers running
MS-DOS, Windows 3.x, and Windows for Workgroups.
Real World Shared Folder Permissions on Large Networks
On small networks, you are likely to find that either Simple File Sharing or shared
folder permissions are used to control access to files and folders on the network.
Even when drives are formatted with the NTFS file system, most people on small
networks just do not use NTFS permissions.
On large company networks, you find just the opposite. Administrators typically
rely on NTFS permissions and leave the default shared folder permissions (or
remove the Everyone group and provide the Users group full access) in place
because NTFS permissions do a much better job of securing data. Because of the
way that shared folder permissions and NTFS permissions interact, NTFS permissions
secure data for both local and network access. Adding shared folder permissions
is really unnecessary and in fact complicates the permissions that
administrators must work with. The exception to this is on computers running
older versions of Windows (for example, Windows 98 or Windows Me) that do not
support the NTFS file system; these systems must use shared folder permissions if
their data is to be shared on the network.
Practice: Managing Shared Folders
In this practice, you will determine the effective shared permissions of users, share a
folder, create an additional share name for a shared folder, and stop the sharing of a
folder.
Exercise 1: Calculate Effective Shared Permissions
In the following exercise, User101 has been assigned permissions to access resources
as an individual and as a member of a group, as shown in Figure 9-7.
