Windows PowerShell cmdlet Grant-DfsnAccess does not change inheritance on DFS links

Applies to: Windows Server 2016Windows 10Windows Server 2012 R2 Standard


You use the Windows PowerShell cmdlet Grant-DfsnAccess to set permissions on Distributed File System (DFS) links in a DFS namespace in order to have the links filtered by Access Based Enumeration, as in the following example:

Grant-DfsnAccess -Path "\\\Software\Projects" -AccountName "Contoso\SarahJones"

Although the command is completed successfully and the result of the cmdlet shows the correct permissions, you notice that the Access Based Enumeration filtering does not reflect the newly set permissions. Additionally, when you check the permissions of the link in the DFS Management Console, you notice that the Use inherited permission from the local file System option is still selected.


Although the Grant-DfsnAccess cmdlet successfully configures the view permissions for individual groups or users, the cmdlet does not change the inheritance mode from use inherited to set explicit. Therefore, the permissions that are set on the link do not take effect.

Microsoft is aware of this problem with the Windows PowerShell cmdlet Grant-DfsnAccess.


To work around this problem, use one of the following methods.

Method 1

Manually disable inheritance in the DFS Management Console by selecting the Set explicit view permissions option.

Method 2

Use the dfsutil property sd grant command instead, as in the following example:

dfsutil property sd grant \\\Software\Projects Contoso\SarahJones:RX protect

More Information

In order to administer DFS namespaces, several Windows PowerShell cmdlets were created as replacement for the command-line utilities such as dfsutil.exe. One of the administrative tasks that is usually automated is the granting of permissions to DFS links for ABE filtering. By default, DFS namespaces inherit the permission from the DFS root down to the links. This is represented in the Microsoft Management Console (MMC) user interface as use inherited permissions from the local file system. However, for certain links to be displayed while other links are not, the administrator has to select the Set explicit view permissions on the DFS folder option and then set the Configure View permissions for the individual users or groups.
