Health Monitor

Explanation

When freezing the Zone file of the Zone, dynamic updates cannot occur. This means that any changes or updates to the Zone file will be restricted, ensuring that the Zone remains static and unchanged during the freeze period.

Freezing the Zone file does not impact normal name resolution. The DNS server will still be able to resolve domain names and provide the necessary information to clients, even though dynamic updates are disabled during this time.
