Restricting Access to Floppy Drives
By Troy Thompson, MCSE+Internet

Floplock is a service that can be used 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 the Floplock service is installed and started, only those users in the groups mentioned above 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.

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

cd\<folder name>

instsrv <service name> <drive>:\<folder name>\floplock.exe
where <service name> is the name you specify for the Floplock service, <drive> is the drive letter in which the Windows NT Resource Kit is installed, and <folder name> is the folder in which the Windows NT Resource Kit is installed.
 

If you want the Floplock service to start automatically when you log on to Windows NT, change the setting to Automatically via the Service icon of the Control Panel.

You can remove the Floplock service by typing

Instsrv <service name> remove

at the command prompt, where <service name> is the name you specify for the Floplock service from the command prompt.
