My experience has been the exact opposite with the Mac, whether its trying to access a share on one of my other computers (my wife uses a PC) or accessing network resources on my work's network.
When in windows 7 it "just worked" I had no need to mess with eth0, drivers or any manually set up a network. I was able to connect to the resource and use it. Also it was much faster.
It has always been the same with the mac. Just go to the finder and look for shared computers.

Taskbar: 'Go To Server/Computer'

I had issues with OSX, that I was unable to access any shared files from my wife's computer. Accessing my work stuff was a bit easier but was SLOW, painfully slow. I pull up a folder with a couple hundred files, and I can easily sit there for well over 10 minutes while OSX does it thing. Windows, just a couple of minutes.
Report bugs. Are you comparing b/w OSX <-> Windows and Windows <-> Windows?
Networking is where windows has a clear advantage of OSX, in part because many (most?) enterprise networks are windows based, at least from my experience.
You are confusing stuff.
Given the design of windows, there's zero chance of that, it would require a complete rewrite and the folks at MS really don't see the design of windows being flawed. Especially since they see the marketshare being what it is - kind of like why fix it if it isn't broke mentality.
Fair enough.
