Symptoms
Consider the following scenario:
-
You configure a stand-alone Distributed File System (DFS) root on a Windows Server 2012-based or Windows Server 2008 R2-based failover cluster.
-
You configure one or more Windows Server 2008 R2-based failover cluster nodes for the DFS resource.
-
You map a network drive to the DFS root on a client computer that is running Windows 7 or Windows Server 2008 R2.
-
When a cluster failover occurs, you try to access the mapped network drive from the client computer by using the Server Message Block (SMB) protocol version 2.
In this scenario, you cannot connect to the mapped network drive. Additionally, you receive an error message that resembles the following:
Title: Location is not available
Body: Path of the folder refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location.Additionally, you still cannot connect to the mapped network drive after the failover occurs until you restart the computer or log off the computer and log on it again.
