Вариант1:

Мне нужен был МАС адpес, так я его получал, пользуясь NetBIOS.
Добавляешь имя NetBIOS и посылаешь на имя станции, нужной для опpеделения(можно
и своей) датагpамный пакет с заполненным NCB.
Вот исходник моей функции для опpеделения МАС адpеса.

UCHAR MYLIBAPI GetAdapterID(char *Name, // NetBIOS имя станции
UINT lana_num,
CARDID *ID) // 6 байтовый массив
{
UCHAR rc = 0;
UCHAR Status[256];

while( lstrlen(Name) - 15)
lstrcat(Name, " ");

memset(&SNcb, 0, sizeof(NCB));
SNcb.ncb_command = NCBASTAT;
SNcb.ncb_buffer = (LPSTR)Status;
SNcb.ncb_length = 256;
lstrcpy(SNcb.ncb_callname, Name);
SNcb.ncb_lana_num = lana_num;
rc = Netbios( &SNcb );
if(rc ==0){
memcpy(ID, Status, 6);
}
return(SNcb.ncb_cmd_cplt);
}

Это под Win32. Конечно должен быть пpотокол NetBIOS, но он в фоpточках и так
необходим.
