RE: Discovering Active Direcory users with blank passwords

Is there a way to discover Active Directory users
with blank passwords 
if I have domain admin privileges and local access
to my domain 
controllers?

One method I've used in the past is to write a Perl
script (I know...) that enumerates the user accounts
from the DC, and then attempts to log in to that
account using a blank password.  It's a one-shot deal,
so it won't lock out the account, and you'll end up
with a nice short list.
