(Domain Controllers) dynamic DNS updates configuration of time RRS feed

  • Question

  • Hello,

    We are facing a specific issue in our AD environment :

    We have 14 DCs that update their records in two external (linux bind) dns servers using dynamic dns updates.

    What we found is all the DCs updates their DNS at the exact same time that sometimes leads to a complete domain unavailability for a few minutes.

    Each days, the exact time of these updates seems to be 06:00, 12:00 and 18:00.

    I created a monitoring of this behavior using nagios and requesting regulary our DNS how many DCs do you have in your records.

    As you can see on the attached picture, it represents, on both DNS, how many DCs they have. Since we have 14 DCs, 28 is the max value.

    You can see here the problem that all DCs getting out of DNS system at the same time...

    I am wondering how can we configure each DC to update its dynamic dns record at specific time so we can achieve to avoid all DCs out of DNS at 6:00, 12:00 and 18:00 

    THanks for any help
