Have you tried regkey
"HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon, AllocateFloppies, 0, REG_SZ" ?

I have not tried, but hack resource indicates value of 0 locks access except for all administrators in the Domain, value of '1' only the user logged on locally can access the floppy disks in the drive.

I have not tried this, nor am I sure a non-Admin can write to this key. Should only work in WinNT/2K. If you try in your test environment, please let the Board know how things went.
