The forwarder is our ISP. In a browser, the site we have requested 
appears with frantic dns output. We then get the 'Not authoritative for forwarding.' message and dns messages stop. s4 messages still 
appear e.g. with kinit but very slowly. We then get:

../source4/dsdb/dns/dns_update.c:294: Failed DNS update - 
And s4 has to be restarted.

No. I was wrong. Restarting s4 gets us back up and running until we hit 
the forwarder again.

Any ideas?
