«Сервер RPC недоступен» при репликации контроллеров домена.

У меня два контроллера домена:

DC1: Win2k3 R2 EGDC1: Win2k8 R2

Когда я пытаюсь воспроизвести эти два (через Manage Sites and Services и под NTDS Settings), выбрав Replicate Now, Я получаю сообщение об ошибке The RPC Server is unavailable. Неважно, попробую ли я это, когда удаленно подключусь к DC1 или DC2.

В соответствии с эта статья в технике, это проблема, когда машина не работает. Тем не менее, я могу дополнительно настроить оба контроллера домена друг на друга, чтобы не возникло проблем с DNS или подключением. Оба находятся в одной локальной сети и даже в одной подсети, поэтому никаких проблем с VPN / Wi-Fi / брандмауэром / причудливыми проблемами не должно быть.

Кроме того, я убедился, что служба RPC работает на обоих компьютерах.

В чем может быть проблема и как ее исправить?

Похоже, последняя репликация была произведена 10 мая, что изменилось? Я предполагаю, что у вас есть какое-то несоответствие в записях SRV в DNS для двух контроллеров домена. Для репликации AD требуется нечто большее, чем просто запись A, которую использует ping, поэтому Ping может дать вам ложный отрицательный результат в отношении работоспособности DNS. Попробуйте настроить оба сервера на один и тот же DNS-сервер и перезапустить службу netlogin на обоих. Затем повторите попытку репликации.

А dcdiag /fix повторно зарегистрирует записи DNS для контроллера домена и исправит это.

Вы можете настроить порт RPC в реестре, после чего его нужно будет перезапустить.

regedit-> local machine-> software-> microsoft-> rpc-> internet, затем измените порт с 5000-5002 по умолчанию на 5000-5200 (минимальная настройка - 200).

С Уважением,

Каждый раз, когда это происходит, я отключаю IPv6 на сетевых адаптерах постоянного тока, и все работает. Хотя лучше всего не отключать IPv6. Джефф

Попробуй это :

Не указывайте локальный сервер как DNS
Бегать ipconfig /flushdns
Перезапустите службу netlogon
Бегать repadmin /syncall /AeDP
