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?

I crack these routinely when pentesting/playing, granted, it's by pushing
the sam through rainbow tables, thus admin access...
Basically, any sam once in hand, is cracked these days via rainbowtables.
There're ways to prevent this from happening, but most admins don't go that
extra step...

You can try to crack them through normal means, but it'd likely be a futile
act since a) they are randomized and *extremely* complex (as far as I
recall) and b) even my ~13 year old knows to restrict these accounts. There
are clueless admins out there though, so, *shrug*.
