Hi Thor

We are professional penetration testers based in the UK but working worldwide, with large corporate clients (many international) in all industry sectors. I conduct a large number of on-site penetration tests every year. To date I have yet to find one client who has consistently implemented Windows passwords/phrases longer than 14 characters and the vast majority have *no* passwords longer than 14. None of these clients have turned off LM compatibility in policy either. I give regular talks at (non-hacker) conferences and find most people have no idea about this issue, despite what you and I both know and have known since W2K came out.

best wishes
Pete
