Cannot access DFS root when the DFS path is offline and you log on to a Windows-based computer for the first time

Symptoms

Consider the following scenario:

  • You configure the following Folder Redirection Group Policy setting to use a Distributed File System (DFS) path as the redirect location or folders:

    Group Policy Object (GPO) name\User Configuration\Policies\Windows Settings\Folder Redirection

  • You disable the following Do not automatically make redirected folders available offline Group Policy setting to make sure that the redirected folders can be accessed when they are offline:

    GPO name\User Configuration\Administrative Templates\System\Folder Redirection

  • You configure the following Configure slow-linkmode Group Policy setting to use slow-link mode for the redirected folders when network latency is greater than a specified value:

    Computer Configuration\Policies\Administrative Templates\Network\Offline Files

  • A domain user logs on to a client computer that is running Windows 8.1, Windows Server 2012 R2, Windows 7 Service Pack 1 (SP1), or Windows Server 2008 R2 SP1.

  • The user uses a redirected folder to transfer files.

  • Network latency is greater than the specified value. Therefore, the redirected folder is transitioned offline, and DFS path is transitioned offline.

  • Another user who did not previously log on to the client computer logs on to this computer.

In this scenario, the Folder Redirection Group Policy setting works correctly. However, the user cannot access the DFS root and cannot see the sync information about the redirected folders in Sync Center.

Note This issue also occurs when the whole DFS path is manually set to point to an offline location. If there is a drive that is mapped to the DFS path, the user also cannot access the drive.
