Although this isn't really an ubuntu thing, download opcrack, rainbow
table cracker for Windows passwords.  Works a treat, I have used it a
few times to get into machines when I have been desperate.  More info
available at http://ophcrack.sourceforge.net/

At least that link gets it back onto the topic of Linux which is kinda
related to ubuntu.
