DHCP cluster lose control over PTR records RRS feed

  • Question

  • Hello!

    I have DHCP cluster (2 nodes, 2012 R2).
    Special account for DHCP configured.
    DNS Dynamic update switch to "secured".

    Problem is.. some leases on DHCP marked as "DNS dynamic update pending",
    but PTR and A records are correct.
    ----

    What are the correct premissions on DNS records in cluster configuration?

    Who have to be owner of record?

  • If Your DHCP server manages DNS records on behalf of Your Clients then you need to either add machine accounts of both nodes to the DnsUpdateProxy Group or create a separate account to be used for DNS updates and configure DHCP service on both nodes to use this account for DNS updates.

  • First make sure Your DHCP servers are configured with "Always dynamically update DNS A and PTR records". If some clients took ownership of their records prior to the change, then you'll need to fix it manually (or delete the records and wait for DHCP to reregister them).

  • I have a separate account.
    But some PCs take owner rights on DNS records, in this case DHCP can't update them.

    Do I need to change rights manually, to fix the problem?
