Как перешли на полупостоянку ISDN маршрутизатор стал изредка зависать. Иногда канал показывает up down, а иногда up up, но результат анологичный - связи нет с интернетом. Начал отслеживать логи и начала проскальзывать ошибка и т.п. Привожу сегоднишний лог:00:00:21: %LINK-3-UPDOWN: Interface Ethernet0, changed state to up

Поэтому есть несколько вопросов: 1. Как сделать чтобы хранились логи на серваке W2k? 2.Что это за ошибка у меня проскакивает? 3. Почему переодически как видно из логов канал падает, а затем возвращается в нормальное состояние?
