Disable “Automatic adjustment of Zone Transfer”
By default, the Men&Mice Suite automatically adjusts zone transfer settings for slave zones. If this is not a desired behavior for your environment, you can disable it:
Log in to the Management Console
Navigate to Tools –> System Settings –> Advanced.
Filter the options with “automatically”, and locate the “Automatically adjust local zone transfer settings for BIND” line.
Uncheck the box to disable.
