I'm pretty sure the XP box is configured correctly for DHCP (no static IP), but 
will check it again. 

By "check the lease information in the DSL modem", do you mean to see if the CM 
IP Address "Expires" date is earlier than current date? I unplugged both the 
modem and the router today before connecting the new FreeBSD box, so I assume 
that they are both "current".

I'll investigate/try all of the things you listed and see if anything turns up. 
I'll also check to see if /etc/rc.conf contains the following entry: 

Is there any way that the NIC on FreeBSD box could get configured multiple 
times (e.g., multiple entries in config files), and if so, could this cause 

If the FreeBSD system were configured as a DHCP server (in addition to the 
router, which definitely is), what would you expect to happen? It shouldn't be, 
but what if it were?

Thank you!

I ran "ipconfig /all" on both Windows boxes and found that the FreeBSD box is 
assigned the same IP address as the Windows XP box (which had that IP address 
FIRST). Why is the FreeBSD box being assigned a non-unique IP address? 

Have you checked the network properties (tcp-ip settings) for the XP machine to 
make sure it's being assigned a dynamic IP address?
Have you tried running ipconfig /renew on the XP machine? 
Have you checked the lease information in the DSL modem?

A DHCP server will not hand out the same IP address twice.
The only time I've seen something like this happen is when the DHCP lease times 
out for an IP and windows doesn't renew the lease on the IP, the IP is put into 
the free-ip's pool and handed out when the DHCP feels up to it... 
So if the XP machine is setup for DHCP, it got the IP via dhcp, it probably 
didn't renew the lease on the IP.

Ahhh...imagining that irresistible "new car" smell?
