A. By default Windows NT allows any program to access the floppy and CD-ROM drives. In a secure environment you may only want the interactive user to be able to access the drives and this is accomplished using the registry:

  1. Start the registry editor (regedit.exe)

  2. Move to the HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionWinlogon

  3. From the Edit menu, select New Reg_SZ type

  4. To allocate floppy drives create a name "AllocateFloppies", to allocate CD-ROM drives "AllocateCDRoms"

  5. Press enter, and then set the value to 1

  6. Logout and login again
