Symptoms

Consider the following scenario:

  • You install the Distributed File System (DFS) Namespace service on a computer that is running Windows Server 2008 R2.

  • You create a DFS namespace that has two target folders. For example, you create the following DFS namespace and DFS target folders:

    • DFS namespace: \\contoso.com\ns1

    • DFS folder: \\constoso.com\ns1\folder1

    • Folder target 1: \\server1\share\

    • Folder target 2: \\server2\share\folder1\

  • You run the following command on the computer or on a Windows 7-based client computer that has the Distributed File System tools installed to set target folder 2 as the active target:

    dfsutil.exe client property state active \\constoso.com\ns1\folder1 "\\server2\share\folder1"

In this scenario, the command does not set the active target. Additionally, you receive an error message that resembles the following:

Could not execute the command successfully.
SYSTEM ERROR - There is no DFS name whose entry path matches the input Entry Path.

Note This issue does not occur when you use the following command to set target folder 1, which does not have subfolders, as the active target:

dfsutil.exe client property state active \\constoso.com\ns1\folder1 "\\server1\share\"

Cause

This issue occurs because Windows does not send the full path of the shared folder when you try to set the active target for a DFS namespace. This behavior prevents the DFS utility (Dfsutil.exe) from setting a shared folder that has subfolders as the active target.
