Setting WINS/DNS/DHCP servers on LAN interface? [*SOLVED*]

[BlueToast]

IP Address. . . . . . . . . . . . : 10.0.1.105
Default Gateway . . . . . . . . . : 10.0.255.250
DHCP Server . . . . . . . . . . . : 10.0.0.69
DNS Servers . . . . . . . . . . . : 10.0.0.69
                                   10.0.255.250
Primary WINS Server . . . . . . . : 10.0.0.69

Currently there is another server on the network that acts as a DHCPd server. How do I migrate this to the pfSense server on the LAN interface? Some kind people at HardForum gave me instructions on finding the other DHCPd servers and how to terminate the service running on those machines, so I know how to do this part.. it's just that if I did it now, the machines wouldn't know which machine acts as the domain controller for the Windows domain. (Note: all servers are Linux.)

EDIT: Nevermind! :D Just go to the DHCP Service page.
