The easiest way is to just spawn an instance of the SUBST command-line
program, which comes with Windows for assigning drive letters to physical
folders on the hard drive.

If you want to handle the creation yourself, then:

Under Win9x/Me you have to call DeviceIoControl() to trigger Int21h function
71AAh via the VWIN32.VXD device driver:

Under WinNT/2K/XP, on the other hand, you can use the DefineDosDevice()
function to create the mapping directly:
