Iam new to C++. С помощью MSDN article iam пытается получить все компьютеры под OU в домене с помощью ADSI. Но Iam получает ошибку 8254L (FILTER_UNKNOWN). Я не уверен, что я здесь делаю неправильно. Я попытался обновить фильтр, но никаких изменений в ошибке. Пожалуйста, предложите, что я делаю неправильно здесь.ADSI Filter Все компьютеры из OU с использованием C++
