3. Policy Removal Considerations

Table 1 summarizes what happens to redirected folders and their contents when a GPO no longer applies.

Table 1. Effects of Policy Removal Options
When the Move The Contents Of Special Folder Type To The New Location setting is...And the Policy Removal option is...Results when the policy is removed are...

  The contents are copied, not moved, back to the user profile location.
  The contents are not deleted from the location they were redirected to.
  The user continues to have access to the contents, but only on the local computer.
DisabledRedirect The Folder Back To The Userprofile Location When Policy Is RemovedThe special folder returns to its user profile location.
  The contents are not copied or moved to the user profile location.
  Caution: If the contents of a folder are not copied to the user profile location, the user can no longer see them.

  The contents remain at the location they were redirected to.
  The user continues to have access to the contents at the location they were redirected to.

4. Folder Redirection and Offline Files

Folder redirection provides users with a central network access point for storing and finding information, and it provides administrators with a central network access point for managing information. However, in the event of a network failure or for users who use portable computers, how will the users be able to access the information in redirected folders? The Offline Files feature provides users with access to redirected folders even when they are not connected to the network. Offline Files caches files accessed through folder redirection onto the hard drive of the local computer. When a user accesses a file in a redirected folder, the file is accessed and modified locally. When a user has finished working with the file and has logged off, only then does the file traverse the network for storage on the server.

Working Offline

If the status of your network connection changes, Offline Files provides notification by displaying an informational balloon over the notification area (lower right corner of the desktop). If the informational balloon notifies you that you are offline, you might or might not be able to continue to work with your files as you normally do. You can click the Offline Files icon in the notification area for more information about the status of your connection.

If you are working offline (either because you are disconnected from the network or because you undocked your portable computer), you can still browse network drives and shared folders in My Computer or My Network Places. A red X appears over any disconnected network drives. You can see only those files that you made available offline and any files that you created after the network connection was lost. Your permissions on the network files and folders remain the same whether you are connected to the network or working offline. When you are disconnected from the network, you can print to local printers, but you cannot print to shared printers on the network.

Once you reconnect to the network, the Synchronization Manager updates the network files with changes that you made while working offline. When you synchronize files, the files that you opened or updated while disconnected from the network are compared to the files that are saved on the network. As long as the files you changed haven’t been changed by someone else while you were offline, your changes are copied to the network.

If someone else made changes to the same network file that you updated offline, you can keep your version, the version on the network, or both. If you delete a network file on your computer while working offline but someone else on the network makes changes to that file, the file is deleted from your computer but not from the network. If you change a network file while working offline but someone else on the network deletes that file, you can save your version onto the network or delete it from your computer. If you are disconnected from the network when a new file is added to a shared network folder that you have made available offline, the new file is added to your computer when you reconnect and synchronize.

Setting Up Offline Files

If you use redirected folders of any type, it is recommended that you set up Offline Files. However, Offline Files does not depend on settings in the Folder Redirection node and is set up and configured on network shares separately from the Folder Redirection configuration. The tasks for implementing Offline Files are:

1.
Configure the sharepoint.

2.
Configure computers to use Offline Files.

3.
Synchronize offline files and folders.

Configuring the Sharepoint

The first step in setting up Offline Files is to configure the sharepoint. You configure the sharepoint in the Sharing tab in the Properties dialog box for the shared folder.

To configure the sharepoint, complete the following steps:

1.
Right-click the shared folder containing the offline files, and select Sharing And Security.

2.
In the Sharing tab in the Properties dialog box for the shared folder, click Offline Settings.

3.
In the Offline Settings dialog box, shown in Figure 4, select one of the following options:

  • Only The Files And Programs That Users Specify Will Be Available Offline. Select this option if you want users to be able to determine which files will be available offline.

  • All Files And Programs That Users Open From The Share Will Be Automatically Available Offline. Select this option if you want all files that users open from the shared resource to be automatically available offline. Select the Optimized For Performance check box if you want to automatically cache programs so that they can be run locally. This option is useful for file servers that host applications because it reduces network traffic and improves server scalability.

  • Files Or Programs From The Share Will Not Be Available Offline. Select this option to prevent users from storing files offline.

Click OK.

5.
In the Properties dialog box for the shared folder, click OK.

Configuring Computers and Servers to Use Offline Files

After you configure the sharepoint, you must configure clients to use Offline Files. Windows 2000, Windows XP, and Windows Server 2003 are able to use Offline Files. You can configure clients to use Offline Files manually in the Offline Files tab in the Folder Options dialog box for each client computer. Or, you can configure users’ computers and servers to use Offline Files by setting policies in Administrative Templates/Network/Offline Files in both the Computer Configuration and User Configuration nodes. This section provides the procedure for manually configuring clients to use Offline Files.

Important

In Windows Server 2003, Remote Desktop For Administration (formerly known as Terminal Services in Remote Administration mode in Windows 2000) provides remote access to the desktop of any computer running a member of the Windows Server 2003 family. Remote Desktop For Administration is installed by default on computers running Windows Server 2003, but it is not enabled by default.

If Remote Desktop For Administration is enabled on a server, you cannot configure the server to use Offline Files because the Remote Desktop For Administration and Offline Files features are mutually exclusive. Therefore, before attempting to configure a server to use Offline Files (for the exercises in this lesson, or in a production setting), you must disable Remote Desktop For Administration. To do this on the server, right-click My Computer and select Properties. In the System Properties dialog box, select the Remote tab. In the Remote Desktop section, clear the Allow Users To Connect Remotely To This Computer check box and then click OK.


To configure computers and servers to use Offline Files, complete the following steps:

1.
Open My Computer.

2.
On the Tools menu, click Folder Options.

3.
In the Folder Options dialog box, click the Offline Files tab.

4.
In the Offline Files tab, shown in Figure 5, select the Enable Offline Files check box. For computers running Windows 2000 Professional and Windows XP Professional, this box is selected by default.

5.
Select the Synchronize All Offline Files When Logging On check box if you want to fully synchronize offline files when a user logs on. Select the Synchronize All Offline Files Before Logging Off check box if you want to fully synchronize offline files before a user logs off. Full synchronization ensures that the network files reflect the latest changes. If you do not select these options, a quick synchronization occurs when a user logs on or off. A quick synchronization provides a complete version of online files, but it might not provide the most current version.

Note

It is recommended that you always synchronize when you log on to your computer. This ensures that changes made on your computer are synchronized with changes that were made on the network while you were disconnected.

6.
Select the Display A Reminder Every check box if you want to provide reminder balloons in the notification area of the desktop (lower right corner) when the computer goes offline. Specify in the Minutes box how often (in minutes) you want the reminders to appear.

7.
Select the Create An Offline Files Shortcut On The Desktop check box if you want to place a shortcut to the Offline Files folder on the desktop.

8.
Select the Encrypt Offline Files To Secure Data check box if you want to encrypt offline files to keep them safe from intruders who might gain unauthorized physical access to the client computer.

Note

This check box is disabled if you are not an administrator on the computer, the local drive is not NTFS or does not support encryption, or your system administrator has implemented an encryption policy for Offline Files.

9.
Select the amount of disk space you want to use for temporary offline files on the slider bar in the lower portion of the Offline Files tab.

10.
Click Advanced.

11.
In the Offline Files–Advanced Settings dialog box, shown in Figure 6, select one of the following options to indicate how a computer behaves when the connection to another computer on the network is lost:

  • Notify Me And Begin Working Offline. Select this option to specify that the user can work offline if the network connection is lost because network files will continue to be available.

  • Never Allow My Computer To Go Offline. Select this option to specify that the user cannot work offline if the network connection is lost because network files will not be available.

Figure 6. Offline Files-Advanced Settings dialog box


12.
Click Add if you want a specific computer to receive a different treatment if the connection to another computer on the network is lost. If you click Add, the Offline Files–Add Custom Action dialog box appears. In the Computer box, type the name of the computer that will receive different treatment. Then select the treatment you want the computer to receive in the When A Network Connection Is Lost section. Click OK.

13.
In the Offline Files–Advanced Settings dialog box, click OK.

14.
In the Folder Options dialog box, click OK.

Synchronizing Offline Files and Folders

You can determine the way you want your computer to synchronize your files when you log on and off the network. There are two ways to set up synchronization of offline files and folders. You can set up synchronization manually by using the Items To Synchronize dialog box, also referred to as the Synchronization Manager in documentation and Help. Or you can set up synchronization by setting policies in Administrative Templates/Network/Offline Files in both the Computer Configuration and User Configuration nodes. This section provides the procedure for manually setting up synchronization of offline files and folders.

To set up synchronization of offline files and folders, complete the following steps:

1.
Click Start, point to All Programs, point to Accessories, and then click Synchronize.

Note

You can also open the Items To Synchronize dialog box by typing mobsync on the command line.

2.
In the Items To Synchronize dialog box, shown in Figure 7, click Setup.

4.
In the Synchronize The Following Checked Items list, select the check boxes next to the offline items that you want to synchronize, such as a folder on a mapped network drive or an Internet Explorer offline Web page.

5.
Select the When I Log On To My Computer check box to synchronize the selected items when the user logs off. Select the When I Log Off My Computer check box to synchronize the selected items when the user logs on.

Note

It is recommended that you always synchronize when you log on to your computer. This ensures that changes made on your computer are synchronized with changes that were made on the network while you were disconnected.

Note

The When I Log On To My Computer and When I Log Off My Computer check boxes are selected by default if you selected the Synchronize All Offline Files When Logging On or Synchronize All Offline Files Before Logging Off options, respectively, in the Offline Files tab in the Folder Options dialog box. These options are part of the “Configure Computers to Use Offline Files” procedure.

6.
Select the Ask Me Before Synchronizing The Items check box if you want Synchronization Manager to request permission before automatically synchronizing your offline items.

7.
Click OK.

8.
In the Items To Synchronize dialog box, click Close.

You can also specify items to be synchronized when a computer is idle by using the On Idle tab in the Synchronization Settings dialog box. By choosing when offline items are synchronized, you can better manage the work on your computer and on the network. Finally, you can schedule when synchronization occurs by using the Scheduled Synchronization Wizard, available from the Scheduled tab in the Synchronization Settings dialog box.

Note

To manually synchronize offline files and folders immediately, right-click the file or folder you want to synchronize, and then click Synchronize.
