Windows XP SP2: Bombarded by firewall messages

Listen to Preston Gralla, one of the long-time journalists who lives and breathes everything Microsoft, talking about Windows XP Service Pack 2, now in testing: "If I were a system administrator or in IT support, I'd be prepared for the worst. The new firewall will be turned on by default, and that means a whole lot of tech support calls and nightmares. Users will be bombarded with firewall messages, and many of their programs will no longer work." This sort of critique must be precisely the reason that Microsoft has delayed releasing XP SP2. The question is, what help will Microsoft give beleaguered networking admins? I'm not sure any wizard Microsoft can write can deal with all those firewall messages.
