поздравляю с открытием списка :)

Вопрос такой: в районной домовой сети "упал" ДНС. Уже почти неделю. 
Админы в курсе, но не чинят, видимо не умеют :(. Видимо, придется 
пользователям писать для них инструкции.

Выглядит падение так:

[alexei@threebears alexei]$ nslookup google.com 10.104.0.1
Server:         10.104.0.1
Address:        10.104.0.1#53

Non-authoritative answer:
*** Can't find google.com: No answer

Т.е. хост не отресолвился. И так со всеми (которые проверял) хостами из 
зон, отличных от .ru. Рунет работает:
[alexei@threebears alexei]$ nslookup lenta.ru 10.104.0.1
Server:         10.104.0.1
Address:        10.104.0.1#53

Non-authoritative answer:
Name:   lenta.ru
Address: 81.19.69.28


Рeзультат dig:
[alexei@threebears alexei]$ dig @10.104.0.1 google.com

Не подскажите, в чем может быть проблема? Или недостаточно информации?
