SFM: Macintosh Locked Folders Are Not Completely Secure

• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

After you either set the Read-Only file attribute or "lock" a folder from a Macintosh computer on a Services for Macintosh (SFM) shared subdirectory, you cannot drag files or folders from the same SFM volume to the locked folder. However, you can copy any other file from any other subdirectory (folder) on the SFM server, copy files from a different SFM server, or copy files from the local Macintosh hard drive to the locked folder.

RESOLUTION

To approximate a locked folder using SFM on a Windows NT Advanced Server computer, set the NTFS permissions for the desired subdirectory (folder) to Read-Only.

For more information on setting permissions on SFM volumes, please refer to the Windows NT Advanced Server Services for Macintosh guide.
