I'll double-check the things you listed. If you can tell me what additional info I need to supply and where to get it, I'll be happy to oblige. Thanks...

Why is the FreeBSD box being > assigned a non-unique IP address? 1. Check that your router's dhcp server is set up properly. 2. Check that the windows box is not set up with a static ip. The box could be hard coded to an ip address and your dhcp server thinks the lease is free. Other than that you need to supply more info.
