Subject: cracking hashes obtained with Login Recovery's boot disk
This question was originally posted under a previous discussion's
Subject, so I've changed the Subject on this response.
This question is barely on topic, but I'll respond this one time.

For those who don't know - this is an online Windows password recovery
service. They offer free download of a boot disk image (floppy or CD)
that dumps the hashes. Then they crack the hashes for you - there's a
free&slow and a non-free&fast option.

John the Ripper does not crack Windows password hashes instantly -
although it will get most passwords really quick in practice. What you
might be looking for is a rainbow tables based cracker such as Ophcrack
or RainbowCrack:

Apparently, Login Recovery's boot disks output hashes in a format
slightly different from pwdump output format that most password crackers
including John the Ripper accept - so trivial format conversion will be
needed first (manual or with a script).
What is your reason to misuse Login Recovery's boot disks like that,
though? Perhaps it'd be easier to either use pwdump2 and JtR or use a
password changing boot disk such as this one:
