Folder Redirection and Offline Files
As discussed earlier in this lesson, folder redirection provides users with central network access point for storing and finding information, and administrators with a central net-work 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.
The special folder returns to its user profile location.
The contents are copied, not moved, back to the user profile location. The contents are not deleted from the redirected location. The user continues to have access to the contents, but only on the local computer.
The special folder returns to its user profile location.
The contents are not copied or moved to the user profile location.
The special folder remains at its redirected location.
The contents remain at the redirected location.
The user continues to have access to the contents at the MCITP Certification redirected location.
If you redirect a user’s Application Data and the user encrypts files or folders using the Encrypting File System (EPS), the user may not be able to decrypt their EPS encrypted folders when they are not connected to the network. This occurs because their encryption keys are stored in the Application Data folder structure. For Windows 2000 Professional systems, network connectivity isn’t an immediate issue because the encryption keys are stored in memory. However, if the user restarts, this can become an issue if network con?nectivity is still not available. For Windows XP Professional systems, loss of network connectivity could become an immediate issue for users trying to decrypt EPS encrypted files because the user’s encryption keys are not stored in memory.
Errors concerning Folder Redirection appear in the Application Log in the Event Viewer on the affected computers. For example, if you attempt to redirect a user’s desktop and select the option Move The Contents Of The Desktop To The New Location, but you fail to give the user permission to write to that folder, the user’s desktop will not be redirected. If that happens, you can find errors in the Event Viewer where the user logged on indicating that the user didn’t have permission to access the folder. To solve the issue, either give the user Write permission to the comptia network desktop or clear the Move The Contents Of Desktop To The New Location check box.
