Tech Tip: Restrict access to floppy drives in Windows NT

Find out how to restrict access to floppy drives.

Floplock is a service that you can use to limit floppy disk drive access to Administrator Group accounts for Windows NT Server, or Administrator and Power User Group accounts for Windows NT Workstation. When you install and start the Floplock service, only those users in the above groups have access to the computer's floppy disk drives.

To install the Floplock service, you must use the Service Installer tool (Instsrv.exe) that comes with the Windows NT Resource Kit.

Follow these steps:

  1. Install Instsrv.exe and Floplock.exe from the Windows NT Resource Kit.
  2. At the command prompt, enter the following commands:

cd\<folder name>
instsrv <service name> <drive>:\<folder name>\floplock.exe

For <service name>, specify the name for the Floplock service. For <drive>, specify the drive letter where you've installed the Windows NT Resource Kit, and specify the folder where you've installed the Windows NT Resource Kit for <folder name>.

If you want the Floplock service to start automatically when you log on to Windows NT, change the service to start automatically via the Services applet of Control Panel.

You can remove the Floplock service by entering the following command at the command prompt:

Instsrv <service name> remove
