This entry restricts access to floppy disk drives to the user currently logged on to the computer. In this mode, floppy disks are allocated to the user as part of the interactive logon process and are freed for general use or for reallocation only when no one is logged on. This parameter satisfies the C2 security requirement that removable media must be securable. Without this restriction, the contents of the floppy disks would be available to all domain administrators remotely.
