    Hello there,

    Create a GPO for the laptops which configures their DNS clients to refresh their DNS records more regularly and sets a short TTL on the records:

    Computer Configuration\Administrative Templates\Network\DNS Client\Registration refresh interval

    Computer Configuration\Administrative Templates\Network\DNS Client\TTL value for A and PTR records

    This way, the laptops can control their own DNS records because DHCP is prevented from automatically doing it on their behalf, plus the short TTL means other machines shouldn't cache any of those records for extended periods.

    Hope this resolves your Query !!
