  22  * Some observations that an automated test can't produce:
  23  * An adapter index is a key for an adapter.  That is, if an index is returned
  24  * from one API, that same index may be used successfully in another API, as
  25  * long as the adapter remains present.
  26  * If the adapter is removed and reinserted, however, the index may change (and
  27  * indeed it does change on Win2K).
  28  *
  29  * The Name field of the IP_ADAPTER_INDEX_MAP entries returned by
  30  * GetInterfaceInfo is declared as a wide string, but the bytes are actually
  31  * an ASCII string on some versions of the IP helper API under Win9x.  This was
  32  * apparently an MS bug, it's corrected in later versions.
  33  *
  34  * The DomainName field of FIXED_INFO isn't NULL-terminated on Win98.
