RE: ntds.dit, john and pwdump2

Hey Soylent, thanks for the tip on Cain.  Nice tool.  However, for future
information, it wants a hashed txt file to crack as well.  It's looking like
the only way to do this is to run pwdump2 on a syskey'd volume and export it
to a file that you can then crack using l0pht, john or cain.

Thanks for all the help.
