Secondary DNS Server takes more than 30 minutes to update records from Primary DNS Server RRS feed

  • Question

  • Hi,

    I have a 2 DCs and 2 Secondary DNS servers (AD integrated zones). Clients are configured to use Secondary DNS Servers - Everything works fine.

    But

    Whenever i make any changes in records of Primary DNS (DCs) it takes atleast 30 mins to update in secondary DNS Servers automatically. If i manually "Transfer from Master"& "Reload" & "Refresh" it updates instantly on Secondary servers -

    Is there any sync cycle in between primary dns server and secondary dns server by default, if so then how can we customize it ?

    In linux its possible but havent found option in dns mmc in windows. However, i got an option to "Notify" in primary server for the zone. will it help ?

    All Servers are 2012 R2.

    Please suggest - Thanks.


    Thanks, Rishi Pandit.

  • Hello,

    Yes, this can be adjusted. The setting you need is called the Refresh Interval. here is an article describing how to configure it: https://technet.microsoft.com/en-us/library/cc783315(v=ws.10).aspx

    • Open the DNS snap-in
    • In the console tree, right-click the applicable zone, and then click Properties
    • On the General tab, verify that the zone type is either Primary or Active Directory-Integrated
    • Click the Start of Authority (SOA) tab
    • In Refresh interval, Retry interval, or Expires after, click a time period in minutes, hours, or days, and type a number in the text box
    • Click OK to save the adjusted interval

    Regards
