Random IP reassignment on Ubuntu

For some reason... my ubuntu box keeps asking for DHCP at random.

Here is the content of /etc/network/interfaces

Does anyone have any idea why it keeps going back to DHCP? Where else should I be checking to make sure that DHCP is off permanently?
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
 
# The loopback network interface
auto lo
iface lo inet loopback
 
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.1.70
netmask 255.255.255.0
broadcast 192.168.1.255
network 192.168.1.0
gateway 192.168.1.1

You can always disable the NetworkManager if you have static networking...

/etc/init.d/NetworkManager stop
update-rc.d -f NetworkManager remove

No Joy. NetworkManager is not installed.

root@asterisk:/home/michael# /etc/init.d/NetworkManager stop
bash: /etc/init.d/NetworkManager: No such file or directory

FYI.... once the IP address goes to 192.168.1.104 (DHCP assigned), all I have to do is /etc/init.d/networking restart and it goes back to 192.168.1.70 like it is supposed to be.

Fixed my own problem.... kind of... I used mac address binding in the DHCP server to always give me the correct ip.
