Helo everyone,
I have some strange problem with my Kerio WinrouteFW. I am using Windows 2008 Server Standard Ed, and I have Active Directory Domain Service installed on it. I am also using Microsoft DNS Service (because of AD).
For Internet connection I am using ADSL. Everything is configured properly and working OK, until next problem occurs:

After 12 hours (I suppose this is time for PPPoE session from my ISP) every client using IE in network cannot open web pages on Internet, and client using Firefox can open but it opens very slow. I checked up error log in Kerio and this is what it reports:

(0) Failed to send DNS query to server xxx.xxx.xxx.20: 10049
Last message repeated 6 times
(0) Failed to send DNS query to server xxx.xxx.xxx.10: 10049
Last message repeated 5 times
(0) Failed to send DNS query to server xxx.xxx.xxx.20: 10049
Last message repeated 5 times
...

1. I have tried disconnect and reconnect PPPoE connection, still reports the same.
2. The same configuration was working in Win2003 without Active Directory Service (I was using Kerio DNS service)
3. When I restart Winroute service, everything is working OK for 12 hours.

Any ideas??

You must disable the DNS forwarder in Kerio WinRoute Firewall in order to be able to use the other DNS server on the some machine.
