When you create a CIFS server on your Storage Virtual Machine (SVM), three default administrative shares are automatically created. You should understand what those default shares are and how they are used.
Data ONTAP creates the following default administrative shares when you create the CIFS server:
Because shares that end with the $ character are hidden shares, the default administrative shares are not visible from My Computer, but you can view them by using Shared Folders.
The ipc$ and admin$ shares are used by Data ONTAP and cannot be used by Windows administrators to access data residing on the SVM.
The ipc$ share is a resource that shares the named pipes that are essential for communication between programs. The ipc$ share is used during remote administration of a computer and when viewing a computer's shared resources. You cannot change the share settings, share properties, or ACLs of the ipc$ share. You also cannot rename or delete the ipc$ share.
The admin$ share is used during remote administration of the SVM. The path of this resource is always the path to the SVM root. You cannot change the share settings, share properties, or ACLs for the admin$ share. You also cannot rename or delete the admin$ share.
The c$ share is an administrative share that the cluster or SVM administrator can use to access and manage the SVM root volume.
The following are characteristics of the c$ share:
This user is the BUILTIN\administrator. By default, the BUILTIN\administrator can map to the share and view, create, modify, or delete files and folders in the mapped root directory. Caution should be exercised when managing files and folders in this directory.
In this case, the administrator must manually create the c$ share.
The c$ administrative share continues to exist and can be used to administer and manage files and folders in the SVM root volume.
