What's New in Offline Files for Windows Vista. Based on customer feedback, the Offline Files feature has been redesigned for Windows Vista. It is intended for general users of Offline Files and system administrators. Before the introduction of Offline Files, Windows users could access files available on a shared network resource only when connected to the network. By using Offline Files, Windows users can access files that are available on a shared network resource and continue to work with network files when the computer is not connected to the network. Offline Files maintains a local cache of remote files and folders on your computer, so that they are available to you when you are working offline. You continue to access these files in the same way that you accessed them when you were online because the shared network resource paths and namespaces are preserved. When your network connection is restored, any changes that you made while working offline are updated to the network by default. Managing user data is a. Re: Slow logon to domain profile while not on network Do you have any mapped network drives -- that tends to slow things down when off the LAN. Logging Off Windows 7A recent experience at a client and a subsequent call from Microsoft PSS highlighted a possible cause for “Slow Log off from Windows 7 and Windows Vista of between. For a detailed explanation about how slow-link mode works in Offline Files for Windows Vista, see "Improved slow. Synchronize all offline files before logging off. More about bit vista running slow. Next off you should run a memory test. Vista started running really slow overnight. Logging Off A ComputerIf you and someone else on the network have made changes to the same file, you have the option of saving your version of the file to the network, the other user's version, or both. Offline Files is useful for. All Windows Vista users who want to be able to continue to access network files if there is a network outage. In Windows Vista, modes of operation apply to individual DFS scopes and individual Server Message Block (SMB) shared folders. A DFS scope is defined as a folder in a domain- based DFS namespace that corresponds to a DFS link. If a network error is detected when connecting to a folder or a file in a domain- based DFS namespace, Offline Files in Windows Vista will not bring the whole domain offline (as it does in Windows XP). It will bring offline only the DFS link that includes the folder or file that had the error. Consider the scenario of the following domain- based DFS namespace: \\DFSdomain\folder. Assume that the namespace has the following configuration. Folder. 2 is a DFS link to: \\server. Folder. 4 is a DFS link to: \\server. If there is a network error connecting to file. The rest of the DFS namespace remains online. If there is a network error connecting to folder. Online mode. Online mode is the default mode of operation, and it provides the following. Normal access to network files. Improved performance because read requests can be satisfied from the local cache if the file in the cache is synchronized with the server. In online mode, all modifications to a file or folder (write, open, or create) are applied to the network server first and then to the local cache. When you are in online mode, the details pane in Windows Explorer shows Offline status: Online. Auto offline mode. When Offline Files determines that there has been a network error during a file operation (browse, open, create, read, or write), it automatically transitions the SMB shared folder or DFS scope where the error occurred to auto offline mode. In auto offline mode, all open, create, read, and write requests are satisfied from the local cache. There are certain operations that you cannot perform while in this mode—for example, changes to the namespace (changing the name of or deleting a folder) or accessing the previous version of a file. However, you can create new folders, continue to browse the part of the namespace that is available to you offline, and also see that part of the namespace for which you only have placeholders. For a detailed explanation about how this works in Offline Files for Windows Vista, see . When a network connection is available, Offline Files automatically transitions to online mode. For more details about what happens during a transition to online mode, see . Other SMB shared resources and DFS scopes will continue to be online. This mode of operation persists even after you restart your computer. Access to files and folders in manual offline mode is the same as in auto offline mode. The difference between these two offline modes is that in manual offline mode, you can initiate a synchronization process for a folder or file at any time. You have the following options. Close the open file before transitioning to offline mode. Ignore the warning. Choose to not go offline. If you ignore the warning and continue with the transition to offline mode, any unsaved changes to the files that have not been cached may be lost. While in manual offline mode, you can return to online mode by clicking Work online on the Windows Explorer Command Bar. For more details about what happens during a transition to online mode, see . This happens if you are working in online mode and the performance of your connection to that SMB shared resource or DFS scope is determined to be low. For a detailed explanation about how slow- link mode works in Offline Files for Windows Vista, see . Unlike previous versions, you do not need to close applications or manually start the synchronization process. When Offline Files in Windows Vista detects that an SMB shared resource or a DFS scope is available for reconnection, that share or scope is seamlessly transitioned to online mode. The transition to online mode of an SMB shared resource or DFS scope works as follows. The namespace for the SMB shared resource or DFS scope is brought online. This ensures that all running applications transition to work with the files on the server. The details pane in Windows Explorer shows Offline status: Offline (need to sync) for that file, and you continue to work with the version of the file that is stored in your local cache. After closing the file, you can use Sync Center at any time to start the synchronization process for that file. This process does the following. Updates (to the server) all offline changes. Updates the local cache with any changes made on the server while you were working offline. During the synchronization process, if Offline Files finds a file that was modified on the server and in the local cache while you were offline, the file stays offline and the synchronization process continues to run. You are notified about the conflict by an icon in the notification area, and the details pane in Windows Explorer shows Offline status: Offline (need to sync) for that file. You can choose to resolve the conflict immediately or at a later time by using Sync Center. Meanwhile, you can continue to work with the version of the file that is stored in your local cache. Optimized file synchronization. One of the performance enhancements of Offline Files in Windows Vista is a faster synchronization process. This is achieved by using a new synchronization algorithm that does the following. Reduces the time and bandwidth needed to identify differences between the local cache and the server. Determines which parts of a file in the local cache have changed, and then updates only those parts of the file on the network server. The process of updating only parts of a file on the server is called Bitmap Differential Transfer. It takes place during synchronization of the local cache to the server. Bitmap Differential Transfer. Offline Files in Windows Vista uses Bitmap Differential Transfer. Bitmap Differential Transfer tracks which blocks of a file in the local cache are modified while you are working offline and then sends only those blocks to the server. In Windows XP, Offline Files copies the entire file from the local cache to the server, even if only a small part of the file was modified while offline. Because Bitmap Differential Transfer can make the synchronization more efficient, Offline Files in Windows Vista supports all file types. Offline Files in Windows XP could not synchronize large files efficiently; therefore, certain types of files were specifically excluded from the local cache. Improved slow- link mode. Offline Files in Windows Vista incorporates a slow- link mode of operation to improve the experience for mobile and traveling users who connect to the corporate network with low- throughput connections. This mode of operation can also improve the experience for users who connect to servers located in remote locations where network latency is high. Performance of a network connection is automatically determined by measuring throughput and packet latency between the client computer and the server that hosts an SMB shared resource or a DFS scope. When low performance is detected, the SMB shared resource or DFS scope is automatically transitioned to slow- link mode. When you are in slow- link mode, all read and write requests are satisfied from the local cache. You can manually initiate a synchronization process at any time by clicking Sync on the Windows Explorer Command Bar, or by using Sync Center. After the synchronization process has completed, you continue to work in slow- link mode. In this mode, all read and write requests are satisfied from the local cache, so Offline Files cannot determine the performance of the network connection. The only way to return to online mode is to manually make this transition. To do this, click Work online on the Windows Explorer Command Bar. After you have transitioned to online mode, Offline Files will reassess the performance of the network connection every five minutes (default setting). If network performance continues to be low, you will automatically be transitioned back to slow- link mode. Enabling slow- link mode. The slow- link mode of operation is not enabled by default. The domain administrator must enable the Configure slow- link mode Group Policy setting. If this policy setting is disabled or has not been configured, Offline Files will not transition an SMB shared resource or DFS scope to slow- link mode. The performance of a network connection is determined by measuring throughput and packet latency between the client computer and the server that hosts the SMB shared resource or DFS scope. You can configure the threshold values for minimum throughput and maximum packet latency in the Configure slow- link mode Group Policy setting. Slow Logoff from Windows 7 and Windows Vista – Mark Parris. A recent experience at a client and a subsequent call from Microsoft PSS highlighted a possible cause for“Slow Log off from Windows 7 and Windows Vista of between 5- 1. Insight: Early Active Directory designs often consisted of an Empty root domain for a multitude of reasons – but primarily for separation of Forest and Domain administration (another topic, for another day). Certain secure Active Directory installations such as those deployed by banks, military and government institutions utilise firewalls to segregate and isolate environments and whilst Domain Controllers can replicate unrestricted between environments – not all Windows clients can communicate with all Domains or Domain Controllers. One issue that this can cause on Windows Vista and Windows 7 clients is slow log off; this is because one time and one time only the Windows client needs to contact the root domain controller to set a registry key detailing the DNS name of the root domain. HKLM\SOFTWARE\Microsoft\Windows. NT\Current. Version\Network. List\Nla\Cache\Intranet. Forests. To resolve this issue you need to either: 1. Open port 3. 89 between the affected clients and the root domain. Set the registry key manually, via a Group Policy Preference, an ADM Template, set the key within your deployment image or scripted build. For newly built machines. Set the DNS name of the forest root domain on. HKLM\SOFTWARE\Microsoft\Windows. NT\Current. Version\Network. List\Nla\Cache\Intranet. Forests. If the machine has contacted the root domain and had the key populated but then was rebuilt – then the settings should be obtained from a client that is functioning correctly, by exporting. HKLM\SOFTWARE\Microsoft\Windows. NT\Current. Version\Network. List\Nla\Then reimporting them to the rebuilt machine ensuring the root domain is still set correctly. Reboot and the issue should now be resolved.
