XP SP2 added a nice capability to limit the number of tcp connections
attempt to 10 per second (this would kill any multithreaded scan), besides,
a patch (I think it was MS05-019) blocked the use of raw sockets.
I'm not sure if the last issue would have an impact on superscan, but the
first one most probably does. There is patch around but I've not tested it.
To be honest, you should try another scanning/testing platform if you can.
XP SP2 and laters will restrict "normal" users from doing things they are
not supposed to to thwart some kind of attacks. This of course happens to
also mess with your work as pentester.
