Chapter 5: At a Glance Procedures (continued)
Limiting Access to a Shared Folder
A shared folder, by default, is open to anyone who has access to your computer. You can limit that access, however, by specifying which groups, individuals, or users of specific computers can access the shared folder, and you can specify the type of access each is allowed.
TIP: Specify users.
If the list of users in the domain is very long, you can type the names you want in the Names box--separating them with semicolons—instead of searching through the list to find the names. Click the Add button, and then click the Check Names button to have Windows 2000 verify the list of individuals.
Change the Access
- Right-click the folder, and choose Sharing from the shortcut menu. Turn on the Sharing option if it's not already selected.
- Click the Permissions button on the Sharing tab.
- With the Everyone group selected, click the Remove button.
- Click the Add button.
- Select the computer, workgroup, domain, or directory that contains the groups or individuals you want to add.
- Select a group, an individual, or a computer.
- Click the Add button.
- Repeat steps 3 through 7 to add more groups, individuals, or computers.
- Click OK.

TIP: New Share button.
Once you've shared a folder, the New Share button appears on the Sharing tab of the Properties dialog box. Click the New Share button to share the folder using a different name and a different set of permissions.
TIP: The NTFS file system.
If you're using the NTFS file system, you can use the Security tab of the folder's Properties dialog box to assign more specific access rights to folders, including shared folders. You can also specify whether a subfolder in a shared folder may also be shared. The Security tab isn't available for folders that use the FAT or FAT32 file system.
SEE ALSO:
For information about additional ways to customize shared access, see "Protecting Individual Files and Folders" on page 282, "Defining Custom Access" on page 286, and "Defining Access Rights" on page 287.
Individualize the Access
- Select a group or an individual.
- For each type of permission, specify the type of access:
- Turn on the Allow check box to permit access.
- Turn on the Deny check box to prohibit access, even if access was granted through a higher-level group (for example, to deny access to an individual even if his or her group has been allowed access).
- Repeat steps 1 and 2 until you've specified the access for all groups and individuals.
- Click OK.
- Click OK to close the Properties dialog box for the folder.

Monitoring Who's Connected
When you've set up your computer to share folders with your coworkers, you can see who's connected to your computer. You can, for any legitimate reason (no, bad moods and power trips are not legitimate reasons), "pull the plug" and disconnect someone from your computer.
TIP: Change the access.
When you've disconnected someone, he or she can reconnect unless you change the access to the shared folder.
Control Who's Connected
- Click the Start button, point to Settings, and choose Control Panel from the submenu.
- Double-click the Administrative Tools icon.
- Double-click the Computer Management icon.
- Expand the System Tools item if it's not already expanded.
- Expand the Shared Folders folder if it's not already expanded.
- Click the Sessions folder.
- Examine who's connected.
- To disconnect an individual, right-click his or her connection, and choose Close Session from the shortcut menu. When prompted, confirm that you want to close the session.

TIP: Quick display.
You can quickly display the Computer Management console by right-clicking the My Computer icon and choosing Manage from the shortcut menu.
TIP: Don't remove sharing.
Some items on your hard disk, such as C$ and ADMIN$, are shared for administrative purposes, and, as a general rule, you shouldn't remove sharing from these items. If you do remove sharing, it will be reestablished when you restart the computer or when the Server service is restarted.
TIP: No System Tools?
If you don't see the System Tools item, use the View window to display the Console Tree.
TIP: Update information.
If you leave the Computer Management console open to monitor shares, press the F5 key to update the information.
Control What's Being Shared
- Click the Open Files folder.
- Examine which files are being used.
- To close a file, right-click it, and choose Close Open File from the shortcut menu.
Control What's Accessible
- Click the Shares folder.
- Right-click a share, and choose the appropriate command from the shortcut menu:
- Stop Sharing to end sharing
- Properties to see more information about the share or to change the share permissions
- Close the Computer Management window when you've finished.

Making Shared Documents Always Available
Connections between computers are not always the best—networks go down, phone lines become disconnected, and so on. To prevent the problems that a broken connection can cause, you can set the shared folder to automatically cache, or store, documents on the computer that's visiting the shared folder. When the connection has been reestablished, you can use the locally stored (cached) documents to update the documents in the shared folder.Set Up Automatic Caching
- Right-click the shared folder, and choose Sharing from the shortcut menu.
- On the Sharing tab of the Properties dialog box, click Caching.
- Verify that the check box to allow caching is turned on.
- Select the type of caching you want:
- Automatic Caching For Documents to specify that any documents being used on the network be cached on the local computer
- Automatic Caching For Programs to specify that any programs and read-only files being used on the network be cached on the local computer
- Click OK.
- Click OK to close the Properties dialog box.

TIP: Speed things up.
Because cached documents are stored and accessed on the hard disk of the connecting computer, caching documents can speed up operations on both the host computer (because the hard disk is accessed less frequently) and the connecting computer (because disk access is faster than network access).
SEE ALSO:
For information about manually selecting which documents or folders are cached for offline use and for information about setting up automatic synchronizing, see "Taking Along Network Files" on page 192.
TIP: No notification?
If your computer is reconnected to the network but Windows 2000 fails to notify you, click the Offline Files icon, and then click OK to synchronize the files. (Clicking OK when you're not connected to the network generates a harmless synchronization error and a message from Windows 2000.)
Use the Files
- Use the files on the share.
- If the network connection is broken, note the information from the Offline Files icon in the status area of the taskbar.
- Continue working with your documents, saving them periodically.
- Note when the connection has been reestablished. When you've completed your work, close any documents that are still open.
- Click the Offline Files icon in the status area of the taskbar.
- Click OK, confirm that the offline files are closed, and wait for the files to be synchronized.
