Гулить можно много,но выдает ошибку соединения с сервером, а это не то:
внезапно перестали отвечать 2 базы (ну т.е. утром пришли, а там - такое). Остальные базы на том же серваке работают как ни в чем не бывало.
Куда копать?

изучайте работу с технологическим журналом.

Поглядел его, ничего не вижу.

ТЖ на сервере или на клиенте смотреть?

7 бед - 1 ресет

врете . вот тема про установку

Ошибка установки соединения 8.3.6.2449

(8) видел. Решения там нет, только тыкание пальцем в небо "авось повезет и это оно". Я и сам так могу.

Т.к. перезапускать сервер ради 2х баз из десятка желания нет - перерегистрировал базу в кластере. Помогло.
