The system cannot stop sharing {0} because it is a highly available (clustered) shared folder that contains shared subfolders, or is a subfolder in such a shared folder.  To stop sharing a subfolder under a highly available shared folder, you can delete the subfolder. To stop sharing an entire highly available shared folder, use the cluster management tools.
