Re: Windows XP / 2K3 Default Users

["Thor (Hammer of God)" <thor () hammerofgod com>]

You "routinely" crack passwords on SAM's that are SYSKEY'd by default
(128-bit) with rainbow tables?  XP/2k3 has syskey on by default... And any
password over 14 characters automatically clear the LM hash, even if you
have not turned it off (which I can't imagine anyone not doing.)

So, I'm guessing that the "rainbow table" hubbub is all 40-bit, or silly LM
hash cracking, right?  Or am I missing something here?
