Chris:
Again, I'm not a network guy, so YMMV. My experience has been that
the computer with the static IP address in the DHCP range of the
router will run with no immediate problems, but the DHCP server
will eventually revoke the lease (because nobody asks for it to be
renewed), then assign it to another computer. Duplicate IP
addresses are never fun to debug!
Thx, Phil Long

FWIW, I've experienced pretty much set-and-forget behaviour from soho /
half-decent routers where you can assign a static IP and they'll respect
the
assignation (or in the cleverer routers, you can fix a static lease). My
previous home Speedtouch TG585v7 could happily do this, as can the
D-Link at
work. (Tomato which I use at home on a WRT54GL these days just ...
Works.)
Surely if a machine has a fixed static IP, it doesn't even enter into
discussion with the network's DHCP server to request a lease? Just the
usual
broadcast traffic...
