Module Name:

    MmcRoot.cpp

Abstract:

    This module contains the implementation for CMmcDfsRoot. This is an class 
  for MMC display related calls for the first level node(the DfsRoot nodes)
  Also contains members and method to be able to manipulate IDfsRoot object
  and add the same to the MMC Console
