Windows DNS server - force A record to update PTR record

Discussion in 'DNS Server' started by Peter Cumming, May 26, 2006.

  1. We have 2 DHCP/DNS servers (Primary/Secondary) to manage our Terminals on a
    private network. Our terminals use DHCP to obtain addressing an in turn use
    dynamic updates to update the DNS server. All is well!

    A new network was created and added to our environment, but a new Reverse
    Lookup zone was not created (forgot!) on the DNS server to allow the DHCP
    Server to dynamicaly update its records. The new terminals were able to add
    an "A" record in he froward lookup zone, but since there was no reverse, we
    cannot do name resolution properly.

    We have since created a new reverse lookup and any new terminals coming in
    are now being added properly to both the forward and reverse lookups and name
    resolution is functioning properly.

    My Question:
    Is there a way to force the terminals that only have a forward lookup record
    entry to automatically update themselves in the reverse lookup zone?
    We tried to use the Update Associated Pointer (PTR) record option under the
    properties of an A record host but it does not seem to work.
    Any suggestions? We do not necesarilly want to have to add each entry
    manually and are looking for a way to force the Reverse zones to repopulate.

    Thank you

  2. Update PTR only works if the PTR exists.
    If DHCP is registering in DNS for the clients, and the clients are XP, use
    repair this connection, if the client registers itself use ipconfig
    /registerdns, if the client doesn't support DDNS, DHCP is registering the
    client, so use ipconfig /release & ipconfig /renew

    Unless you have an application that requires a reverse lookup IP to name
    reverse lookups are not really required for normal connectivity.
