DNS Server Problems - Keep having to restart the DNS service

For about a week now during the day our office internet connection goes
down. When it goes down I have to restart the DNS service on our server
which brings the internet back online.

Our DNS server has forwarders set-up to send external requests to an
external internet based DNS server. We use NAT to share internet access
throughout the office.

When the connection goes down we can access websites by using IP
address. This obviously confirms the problem is DNS based.

Whilst restarting the DNS service on our server sorts the problem I do
need to find out what's causing it to go down.

There are no errors or warning messages in the event log.


Any advice welcomed!
