DHCP doesn't automatically update DNS Forward Lookup Zone. Missing several records. RRS feed

  • Question

  • Dear Experts,

    I read from MS that DHCP, by default, updates the Reverse Lookup Zone first if it exists and ours does, but we're missing a heck of a lot of Forward Lookup Zone records.  We use DHCP, no reservations.  Any ideas as to where I can start my troubleshooting?  DHCP or DNS?  Which settings?  We have an AD integrated-zone and I was thinking that maybe since we don't do any zone transfers, that our reverse lookup zone doesn't transfer anything to our forward lookup zone.  Or does that not matter and are two totally different things?

    Thanks!

  • Hi,

    There is no direct relationship  between Reverse Lookup Zone and updating DNS Forward Lookup Zone.

    In general, Reverse Lookup Zone contains a lots of PTR records. The pointer (PTR) resource record , in contrast to the A resource record, maps an IP address to an FQDN.

    In a full zone transfer, defined in the original DNS specifications, the master server for a zone transmits the entire zone database to the secondary server for that zone.

    If you want to troubleshooting, I suggest you check your dns debug log and DHCP log.

    More information about dns and dhcp log,  please refer to the following article:
