Enable Always Offline mode for faster access to files

  • บทความ

This document describes how to use the Always Offline mode of Offline Files to provide faster access to cached files and redirected folders. Always Offline also provides lower bandwidth usage because users are always working offline, even when they are connected through a high-speed network connection.

Prerequisites

To enable Always Offline mode, your environment must meet the following prerequisites.

  • An Active Directory Domain Services (AD DS) domain with client computers joined to the domain. There are no forest or domain functional-level requirements or schema requirements.
  • Client computers running Windows 10, Windows 8.1, Windows 8, Windows Server 2016, Windows Server 2012 R2, or Windows Server 2012. (Client computers running earlier versions of Windows might continue to transition to Online mode on very high-speed network connections.)
  • A computer with Group Policy Management installed.

Enable Always Offline mode

To enable Always Offline mode, use Group Policy to enable the Configure slow-link mode policy setting and set the latency to 1 (millisecond). Doing so causes client computers running Windows 8 or Windows Server 2012 to automatically use Always Offline mode.

Note

Computers running Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008 might continue to transition to the Online mode if the latency of the network connection drops below one millisecond.

  1. Open Group Policy Management.
  2. To optionally create a new Group Policy Object (GPO) for Offline Files settings, right-click the appropriate domain or organizational unit (OU), and then select Create a GPO in this domain, and link it here.
  3. In the console tree, right-click the GPO for which you want to configure the Offline Files settings and then select Edit. The Group Policy Management Editor appears.
  4. In the console tree, under Computer Configuration, expand Policies, expand Administrative Templates, expand Network, and expand Offline Files.
  5. Right-click Configure slow-link mode, and then select Edit. The Configure slow-link mode window will appear.
  6. Select Enabled.
  7. In the Options box, select Show. The Show Contents window will appear.
  8. In the Value name box, specify the file share for which you want to enable Always Offline mode.
  9. To enable Always Offline mode on all file shares, enter *.
  10. In the Value box, enter Latency=1 to set the latency threshold to one millisecond, and then select OK.

Note

By default, when in Always Offline mode, Windows synchronizes files in the Offline Files cache in the background every two hours. To change this value, use the Configure Background Sync policy setting.
