DHCP Problem [solved]

I'm installing Arch Linux on a laptop and I'm having some trouble with DHCP.
When dhcpcd starts, it prints "err, eth0: ARPOP_REPLY received from 192.168.0.100 (MAC_ADDRESS)" indefinitely.
My rc.conf contains

eth0="dhcp"
INTERFACES=(eth0)

When I checked my router's log, I found this:

Apr/01/2002 03:34:50     DHCP release IP 192.168.0.100
Apr/01/2002 03:34:50     DHCP lease IP 192.168.0.100 to tomato
Apr/01/2002 03:34:40     DHCP release IP 192.168.0.100
Apr/01/2002 03:34:40     DHCP lease IP 192.168.0.100 to tomato
Apr/01/2002 03:34:30     DHCP release IP 192.168.0.100
Apr/01/2002 03:34:30     DHCP lease IP 192.168.0.100 to tomato
Apr/01/2002 03:34:20     DHCP release IP 192.168.0.100
Apr/01/2002 03:34:20     DHCP lease IP 192.168.0.100 to tomato
Apr/01/2002 03:34:10     DHCP release IP 192.168.0.100
Apr/01/2002 03:34:10     DHCP lease IP 192.168.0.100 to tomato

"tomato" is the hostname of the laptop I installed Arch on.
Apparently, it's acquiring an IP addres via DHCP and then immediately releasing it for no reason and starting all over.
Why is this happening?

Edit: I figured it out.  I had unplugged my router for a minute, which caused it to clear the list of DHCP leases.  The router kept assigning the IP "192.168.0.100" to the laptop, which was already in use by another computer on the network.  dhcpcd detected the IP adress confilct and released the DHCP lease, only to get the same IP when it queried the router again.
