be careful:

overwriting the pw offline will work with efs on w2k.
it will not work with winxp/2003: you cant access any efs-data after 
resetting the password offline.

you'll have to crack the usesrs or the admins pw and either logon 
interactively or export their keys to get access to the efs-encrypted
data.

Do you know how his will work for a machine that is part of a Domain?
Where there are no Local Users and the Default Recovery Agent is the
"Domain Admin"

I know tht one can always hack the local admin PW, then unjoin the
domain, but where does that leave the machine.
Is there any way to hack the "nounce" PW?

Thanks

Tim
