This security setting determines whether a CD-ROM is accessible to both local and remote users simultaneously. If this policy is enabled, it allows only the interactively logged-on user to access removable CD-ROM media. If this policy is disabled and no one is logged on interactively, the CD-ROM can be accessed over the network. Default: This policy is not defined and CD-ROM access is not restricted to the locally logged-on user. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options!Devices: Restrict CD-ROM access to locally logged-on user only (2) REG: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon!AllocateCDRoms
