Specifies whether the DHCP server discards forward DNS lookups for clients when a lease expires.
- Dynamically update DNS A and PTR records for DHCP clients.
Specifies whether the DHCP server sends dynamic updates to the DNS server for DHCP clients that do not support performing these updates. If selected, clients running earlier versions of Windows are updated by the DHCP server for both their host (A) and pointer (PTR) resource records.

Toggling DHCPv6 Management On and Off
There is only one DHCP service on a Microsoft DHCP server. DHCPv4 and DHCPv6 are not decoupled in Microsoft as they are in Micetro. Any action performed on either DHCPv6 or DHCPv4 that requires a restart of the service will result in a restart of the single DHCP service on the Microsoft server.
On the Admin page, select the relevant Microsoft DHCP server.
On the Action menu, select Edit service. You can also select this option on the Row menu (…).
Select Manage DHCPv6 service to enable DHCPv6 management on the server(s) you selected.
The Reconcile DHCP Scopes option is used to fix inconsistencies between information in the registry and the DHCP database. For more information about how to reconcile MS DHCP servers, see Reconcile Scopes.
