What kind of cable connection is this? If it's a standard home account
you probably don't have a "real" hostname. The DHCP server will
undoubtably assign you a name like "dhcp-192-168-5-7.verizon.com"
Fortunately, you can get away with a lot without this being truely
"correct". Unless you're trying to host a mail/web/etc server with
this machine.

Pretty typical. My ISP attempts to provide a domain name as well
(dhcp is pretty configurable, in that it can dictate a lot of config,
or only the bare minimum)

That's odd. You can manually set the DNS servers by editing
/etc/resolv.conf and chaning the DHCP config not to update this
file, but your ISP should be providing correct information here.
Are W2K and FreeBSD getting their config from the same DHCP server?
It's possible that your ISP uses multiple DHCP servers, and some
of them are configured wrong.

Looks like something is wrong with your ISPs routing. Seems like you're sending
data int the correct direction, but one of the routers is dropping the ball.
Did you say that all works properly with W2K? This is pretty strange.

This looks OK to me. Your default router is 192.168.241.1, and the routing
knows the MAC address of it. Loopback looks OK, and the netmask seems well.

Unfortunately, it looks as if you've got everything correct. With the
information you've provided, my first guess would be that your ISP is
having trouble with routing. Maybe wait out the problem and see if they
resolve it?
