Offline files can be utilized by mobile users to appear as though a connection to the network is still present. Files are cached on the disconnected remote computer until connectivity to the network is available. If the user loses a connection to the network, or the mobile computer is not connected, the view of shared network items that have been made available offline remains just as if the computer is still connected. Offline files continue to perform as offline even if connected to the network over a slow connection (link).

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\NetCache\SlowLinkSpeedNOTE: The HKEY_LOCAL_MACHINE value overrides the HKEY_CURRENT_USER value if both are present. The value represents bps divided by 100, so the default value of 64,000 is stored as 640 in the registry.
