JSI Tip 2077. Passprop helps prevent break-ins.

Supplement 4 of the Server Resource Kit contains passprop.exe, a tool that helps you tighten security two ways:

PASSPROP [/complex] [/simple] [/adminlockout] [/noadminlockout]    /complex            Force passwords to be complex, requiring passwords                        to be a mix of upper and lowercase letters and                        numbers or symbols.    /simple             Allow passwords to be simple.    /adminlockout       Allow the Administrator account to be locked out.                        Once the account is locked out, as in response to an attempted break-in,                        it can still log on interactively on domain controllers.     /noadminlockout     Don't allow the administrator account to be locked out.

If you type passprop without any parameter, it displays the current state of these settings.
