Hi Jose,
The system is a Samsung ARM s3c2410 with enc28j60 as the ethernet controller. I did not set the ARM system clock because I did not think it mattered. However, I've rectified the situation and the problem remains:
**********************
lease {
interface "eth0";
fixed-address 192.168.1.6;
option subnet-mask 255.255.255.0;
option routers 192.168.1.1;
option dhcp-lease-time 86400;
option dhcp-message-type 5;
option domain-name-servers 192.168.1.1;
option dhcp-server-identifier 192.168.1.1;
renew 1 2012/02/06 03:07:26;
rebind 1 2012/02/06 14:49:21;
expire 1 2012/02/06 17:49:21;
}

and it still still doesn't bind
*******************************
#ifconfig -a

Is this a bootp lease? If not, there may be a problem with system clocks, as your lease appears as expiring in 1-1-1970.
