Алексей1153++ - я ее заблокировал. Сразу после поста. Ну а ты перенес заблокированной.
Собственно ларчик просто открывается. Начиная с w2k в каждой системе есть поддержка интерфейсов Active Directory, в том числе и диалоги выбора пользователей, компьютеров и т.д.. Причем вызовы функций NetXXX в конечном итоге обращаются именно к этим интерфейсам (Рихтер). Ниже пример из MSDN открывающий диалог выбора компьютера. Изменив пару фильтров можно достичь ответ на вопрос этой темы.
