I've recently set up a server running Zentyal 5.0.7 and everything seemed to be running smoothly. However in the last week or so, DNS has seemed to stop working correctly and trying to restart the DNS module leads to a failure.
From looking through the logs it seems to be failing due to "nsupdate".
I'm unsure as to how to go about fixing this issue and after a fair few hours of trying i've decided to turn to the forums for help, so if anyone has a solution to this it would be greatly appreciated.
