You cannot access offline files that were configured in a DFS namespace on a Windows 7-based client computer

Platí pro: Windows 7 EnterpriseWindows 7 Home BasicWindows 7 Home Premium


Consider the following scenario:
  • You have some offline files that were configured in a Distributed File System (DFS) namespace.
  • You perform one of the following operations:
    • You resume the computer from Sleep (S3) mode or from Hibernate (S4) mode.
    • You disconnect from and then reconnect to the network on the computer.
In this scenario, you cannot access the offline files in Windows Explorer on a Windows 7-based client computer.

Additionally, when you click an offline file or a parallel folder that contains contents that are located in the DFS namespace, you receive an error message that resembles the following:
Location is not available.
Can't access <Drive>:\<Folder>.
This file is currently not available for use on this computer.

Note This issue occurs until you restart the client computer.
