Symptoms
Consider the following scenario:
-
You start the Services for Network File System (NFS) on a server that is running Windows Server 2008 R2.
-
You share a folder on the NFS server.
-
You enable the KeepInheritance registry value to set inheritable access control entries (ACEs).
-
You create a child object on the NFS share from an NFS client. For example, you create a file or sub-folder on the NFS share.
In this scenario, the inheritable ACEs may not be propagated correctly to the child object. If a legitimate user tries to access the child object on a client, the user receives an “Access is denied” error message.
Note The issue does not occur in Windows Server 2008.
Cause
This issue occurs because of an issue in the Server for NFS kernel driver that is included in Windows Server 2008 R2. Therefore, some flags are not set correctly on the child objects.
