You can now find two more videos on building both client and service in native C/C++ code on Windows Server 2008 R2. There are on the channel 9: http://channel9.msdn.com/tags/WWSAPI. The videos show step by step creation of a client and a service from the sample I used during TechEd 2009. You can find source code for this sample with instructions on how to build it here. Try it out and let me know of any comments.
