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.
