Symptoms
Consider the following scenario:
  • On a file server, you create a shared folder that contains NT file systems (NTFS) alternate data streams.
  • On a Windows-based client computer that has a network connection to the file server, you enable the Offline Files feature on the shared folder. Therefore, the contents of the folder are cached locally on the client computer.
  • On the client computer, you disconnect the network connection from the file server, and then you modify or rename the shared folder.
  • You re-connect the client computer to the file server, and then you synchronize the shared folder to the file server.
In this scenario, the alternate data streams are lost.

This problem usually occurs when the client computer is running one of the following:
  • Windows XP
  • Windows Server 2003
  • Windows Vista
  • Windows Server 2008
Cause
This behavior occurs because the Offline Files feature does not support alternate data streams.
Workaround
We recommend that you not use alternate data streams on shared folders that have the Offline Files feature enabled.
Status
This behavior is by design.
