ok, lemme try to explain with my limited knowledge since i haven't got my wi-fi card yet. The drivers just allow the OS to see it. To be "Zero Config" as WM 2003 supports the drivers have to be written a special way. Now with that said, what if your drivers aren't written specially for WM 2003. Odds are they'll work but you'll have to use the program that came with it to set up the options... i'm guessing Zero Config would be built into windows (as it is in Windows XP but if the drivers aren't written correctly then you have to use the program because that option doesn't show up when you check out network connections in XP)
here's an example of the program:
and here's an example of Wirless Zero config:

So there if that helps...
