How can you use DHCP policies to block access to certain devices? RRS feed

  • Question

  • Hi there,

    I've read in several places that DHCP policies were used to block computers from getting IP addresses from the DHCP service.

    But as far as I know DHCP policies are only used to provide options to DHCP clients.

    cf. Exam Ref 70-741, Networking with Windows Server 2016 (Andrew Warren) page 73

    So am I right to assume that we've got a misunderstanding here

    https://social.technet.microsoft.com/Forums/en-US/8649dde9-1ba6-41ee-be9a-b31ae63c7db7/dhcp-policies-vs-filters?forum=ws2016

    and here

    https://blogs.technet.microsoft.com/teamdhcp/2012/08/22/dhcp-policies-in-windows-server-2012/

    and instead should have mentioned DHCP filters only.

  • Hi

    You can use Scope policies to Allow or Deny- Machines on the network.

    Or please follow this link

  • Hi N_Seth,

    I coulnd't find the info you were stating on the page you linked: https://www.petri.com/dhcp-policy-based-assignment-windows-server-2012.

    There is only mentioned that DHCP policies can be used to "assign specific IP addresses or DHCP options".

    If I search for "deny" on the page I don't even get a single result.

  • Hi Zoe,

    thanks a million.

    My mistake was that I didn't think of the range specified in a DHCP policy to be excluded from the range specified in the DHCP scope. So a DHCP policy is also creating a DHCP exclusion range for the hosts not compliant with the set conditions.

    Kind regards,

    Dequester
