Some files and folders that are not configured to be cached (that is, to be made available offline) may be cached anyway. The CSCsniff tool shows that these files and folders have been system pinned
(that is, Windows has automatically requested them).Note
The CSCsniff tool is a Microsoft Product Support Services (PSS) internal tool that support professionals can make available to customers for troubleshooting Offline File issues.
This problem may occur if a file or folder that is configured to be cached contains a link to a file or folder that is hosted on a Distributed File System (DFS) share. The administrative caching algorithm (the admin-pin code) does not check to see whether a link target is “cacheable” before pinning it.
The following configuration allows files and folders to be cached:
- The Disable user configuration of Offline files policy setting is enabled.
- The Disable "Make available offline" policy setting is enabled.
- The files and folders are listed in the Administratively assigned offline files policy setting.
- The DFS shares are not explicitly configured to switch off the caching settings (that is, the Allow caching of files in this shared folder setting is enabled for these shares).
With this configuration in place, only the files and folders that are listed in the Administratively assigned offline files
setting should be cached. The content of the DFS shares should not be cached because the first two policy settings prevent users from making files and folders that are on DFS shares available for offline use.
However, if the files and folders that are listed in the Administratively assigned offline files
setting contain shortcuts (links) to files or folders that are located on the DFS shares, the linked-to target files or folders are also cached. This occurs even though the Windows Offline Files feature does not fully support the caching of files and folders on DFS shares.
