I have set the DHCP Up with a subnet

The range type is "Dynamic BOOTP and DHCP"

DNS Update Options is "Always Update"

Whe an IP address is assigned to the client and name gets put into the

HOST Name portion of the IP Address Addressing TAB
But no Host gets created in the DNS Server

Whta do I need to do to make this happen

Under Address type I see an option for Dynamic DHCP with Automatic
Hostname generation thta gives the ability
to fill in an auto host name starts with - is this what I need to

I have another network, its own tree and this specif option is not
avalable - Why
