Jim, The problem is that it is _my_ laptop that needs to work from the IP and DNS addresses it gets from a DHCP server. Right now I have it configured to get the IP address from the DHCP server and the DNS address is hard coded to the 2003 server. Earlier this week I took my laptop out on a service call and forgot that I needed to take out the fixed address. I wasted my time figuring out that the problem was in my machine configuration instead of the client's system!
At this point I think I will enable DHCP on 2003 server to a non-overlapping range of address and see if a switch and 125 feet of cable are enough to ensure that my laptop gets its addresses from the 2003 server rather than the router.
