  • DNS or DHCP issue?

    Hi Pros,

    Would like to check with you all on something.
    My DHCP is set to renew every 7 days.
    And my DNS seems like behaving funny.

    I can have 2 computer names having the same IP Address but 1 of it shows the dated was say 1st August and the other 1 is showing 17th September.

    I have a few of these entries in the DNS showing the same behaviour. What can I do to let the DNS to get updated IP Address and remove those that say not communicating after 1 week?

    Enable DNS scavenging (right click DNS server and select Set Aging/Scavenging...)

      I use the following settings for my DHCP server:

      DHCP > server.domain > IPv4 (right-click and choose Properties) > DNS tab configuration:

      Enable DNS dynamic updates... Always dynamically update DNS A and PTR records

      and

      Discard A and PTR records when lease is deleted.
