A road named NoNameUno

Now that I've test bed setup as desired, I will go thru first bit of stack walk. Note that it is manual stack walk using debugger ... As you can see that it is the receive side stack, when I fire the echoclient user mode app from my dev machine to the target machine I'm debugging. It is a receive side stack, and it does not have the presence of echosrv ( the wsk client, it is a server in client server terminology, but it is a client to the wsk provider if that makes you feel better ). Comments are imbeeded, and we should read it bottom up ... Main idea is to trace the mechanics of the work, rather than delving into the detail of the internal functions of Windows kernel after disassembling.  Note that the comments on the following stack traces are to build the context for understanding without much details. Continue ...
