While you can change the banners for some of these products, and it's not
such a bad idea to do it, there are a large number of other ways that your
servers leak information about what software and windows version they're
running, so that there are other things you will want to do. Your 404 error
page probably does this; if you're running any .ASP pages, that's a
giveaway; tools such as nmap and queso can send a specially crafted packet
to your server and tell your windows version from the response. Also note
that hackers and worms often don't bother to check any more what version of
software you're running before they attack.
I've got more info on this at work, I'll try to remember to post it on
Monday.
