DNS Caching and Windows XP

I recently returned from yet another trip to China (this time with my wife :) and plugged the laptop back into the work network. When I have the laptop in the office I usually use Remote Desktops to connect to it. When I do this I also try to use the wired connection vs. the 802.11b as it is more responsive. What I noticed was that even though the new IP address for the NIC was registered with the DNS server, it was using the old IP Address on my desktop. The effect was that the machine was unreachable.

Using our trusted friend google I found this article to explain how to adjust the DNSClient on the local workstation.
