  30  * This file contains a first attempt for reactos network configuration
  31  *
  32  *  - It is not complete.
  33  *  - It does not work the way it works on Windows.
  34  *
  35  * A lot of code that can be found here now, will probably be relocated into the OS core or some
  36  * protocol Co-Installers or Notify Objects later when all the required COM
  37  * and "netcfgx.dll" infrastructure (esp. headers and Interfaces) get implemented step by step.
  38  *
  39  * This code is only a first approach to provide a usable network configuration dialogs for
  40  * the new network support in Reactos.
  41  *
  42  * If you intend to extend this code by more, please contact me to avoid duplicate work.
  43  * There are already resources and code for TCP/IP configuration that are not
  44  * mature enough for committing them to CVS yet.
