Error message when you try to access a network drive that is mapped to a DFS shared folder on a client computer that is running Windows Vista or Windows Server 2008: “Error: Location is not available”
Consider the following scenario in a network environment:
- A domain-based Distributed File System (DFS) root is hosted by multiple domain controllers.
- A DFS shared folder is linked to a network share that resides on another server.
- On a client computer that is running Windows Vista or Windows Server 2008, you map a network drive to the DFS shared folder.
- The domain controller to which the client computer is connected goes offline.
- You restart the client computer.
In this scenario, it takes a long time to log on to the client computer after it restarts. After you log on to the client computer, you try to access the mapped network drive. However, you cannot access the drive, even though the other domain controllers and the server that hosts the network share are available. Additionally, you receive following error message:
Error:Location is not available Drive:\ is not accessible. The network location cannot be reached. For information about network troubleshooting, see Windows Help.
