Consider the following scenario:

• On a Windows Vista-based computer, you download some files from a network share to an offline folder.
• During this process, some network problems occur, such as a loss of the wireless connection or network congestion.

In this scenario, the files that you download are corrupted.

The corrupted files have the same file size and the same metadata as the original files on the network share. However, when you perform a binary compare, you find the files do not match the original files.

Consider the following scenario:

• You have an offline folder on a Windows Vista-based computer.
• You run an application that uses a client-side caching API to put this folder into suspend mode.

In this scenario, you expect that only this application can be used to make the offline folder work online. However, in Windows Explorer, the Work Online button remains visible and functional for the offline folder.

In an Active Directory domain environment, you configure the “Prohibit ‘Make Available Offline’ for these files and folders” Group Policy setting to prevent domain users from making files or folders available offline. When this Group Policy setting is applied to a Windows Vista-based client computer, the Always available offline check box is still visible in the Properties dialog box of the network share.

However, when a user tries to make the network share available offline, the action fails. Additionally, the user receives the following error message:

This file does not have a program associated with it for performing this action. Create an association in the set associations control panel.

Note: The Group Policy setting successfully removes the Always available offline check box on a Windows XP-based client computer.

This article introduces a hotfix that contains a design change for Windows Vista. In the release version of Windows Vista, you cannot delete or rename the Offline Files when you work offline. After you apply this hotfix, you can delete or rename the Offline Files when you work offline.

Consider the following scenario:

• On a Windows Vista-based computer, you redirect the Documents folder to a shared folder, and you make the Documents folder available offline.
• The computer has network connections. However, the computer cannot reach the shared folder in the current network environment.

In this scenario, the system is frequently unresponsive for 30 seconds. This behavior occurs regardless of whether you are accessing the files in the shared folder that is unreachable. For example, the system may become unresponsive when you try to open Windows Explorer or other applications.

You open the root directory that contains offline files on a Windows Vista-based computer. When you try to synchronize the offline files with the file server for the first time, the synchronization is unsuccessful. In this situation, Windows Vista does not resume the synchronization. Additionally, when you click the offline files that are not synchronized, you receive an access denied message.

Note: When the synchronization is unsuccessful, Windows Vista creates broken branches of the synchronization tree.

On a Windows Vista-based client computer, you can still access offline files even though the file server is removed from the network. Additionally, you cannot delete the offline files and the temporary files in the Offline Files item in Control Panel.

On a Windows Vista-based client computer, you can still access offline files even though the file server is removed from the network. Additionally, you cannot delete the offline files and the temporary files in the Offline Files item in Control Panel.

On an offline Windows Vista-based client computer, you may be unable to delete the cache of offline files from the client-side caching (CSC) cache.

Note: This issue occurs when the offline files are ghost items. Ghosting is a new feature for offline files in Windows Vista. When only partial file contents are cached, or when partial directory contents are cached, CSC creates ghost items. Ghost items cannot be deleted. Additionally, the ghosting feature cannot be disabled in Windows Vista.

Consider the following scenario:

• You set up an offline files synchronization partnership between a Windows Vista-based computer and a network share. After you do this, the files on the network share are copied to the Windows Vista-based computer.
• When you work offline, you update both the network share and the copy.
• When you try to synchronize the network share and the copy, you receive an error message that resembles the following:
  

  Sync conflicts have occured

• In Windows Vista Sync Center, you use the Keep both versions option to resolve the conflict.

In this scenario, Sync Center indicates that the conflict has been resolved and that the synchronization is successful. However, when you synchronize the network share and the copy again, you receive the same error message.

This problem occurs if you use the Keep both versions option while you are working offline.
