Hello Marc,

you need to know your machines ID on the network, once you do simply insert 
this line in /etc/dhclient.conf

interface "rtk0"{
send dhcp-client-identifier "xxxxxxxxx";
}

replace "rtk0" with your network device (dmesg|more and find it there if you 
do not know it) and replace xxxxxxx with your machines ID on the network.

with the line:
dhclient=YES
in your /etc/rc.conf you should be ready to go.

/etc/rc.d/dhclient start

alternatlivly if you are given a static IP address you can configure your 
network device manually.

hope this helped

peace
pete
