Всё о DNS - [16] :: В помощь системному администратору

Приветствую. Помогите тупому пожалуйста.

Имеется сервак с двумя сетевухами (192.168.0.10 и 192.168.0.20). Первая получена путем спаривания двух посредством nVidia DualNet. На серваке стоит:

- Windows Server 2003 R2 Enterprise
- Первичный контроллер AD
- DNS
- DHCP
- WINS
- IIS (На 192.168.0.10)
- WSUS 3.0
- Apache (На 192.168.0.10)
- Adobe Version Cue Server CS3 (он на Tomcat)
- VMware Server 1.0.4

Все работает отлично, но периодически DNS падает со следующмми криками:

Код:

Это же самое он выдает при рестарте сервера. Закономерности я не усмотрел. Мозг мой сломан.
