Thanks for your insight Bob, i'll try it.  On that note, any ideas on:
 AnsiString T.
  T =  (Variant(NetAdapter.pdispVal)).Exec(PropertyGet("IPAddress"));

This doesn't give a compile error but bombs out in runtime with a "Invalid
variant type conversion error".  IPAddress contains an array of type String
which contains the IP address(es).
