The purist would say having non-unique passwords for common accounts is a vulnerability itself, never mind how you set them! ;o) For those who can't afford the likes of CyberArk to manage all passwords individually, pass-the-hash attacks should be considered carefully. Allowing the password to be in a world-readable location for a week would be foolish in many environments (eg. callcentres, educational facilities, etc.) and an audit finding in most regulated ones. Make sure you consider the many "aggravating" factors that might make the risk an external one too ... poorly secured network integrated wi-fi, un-monitored ethernet points with public (or at least non-staff) physical access. You get the gist! a

I'd probably let it slide though, especially in a small environment.

My mitigation is to use the GPO for a week then nuke it, as our standard builds show follow the new PW convention and the GPO is to just catch up the previously-built systems. Thoughts?

Our "local admin maintenance GPO" does two things: * Renames the local admin account. * Sets the password on the added-in local administrator account. Dave From: ed ziots [mailto:[email protected]] Sent: Sunday, January 15, 2012 2:49 PM To: NT System Admin Issues Subject: RE: Quarterly Admin password change +1, that is pretty easy one. Also make sure you rename it to something else than "Administrator" and create a dummy admin account which is only a "Guest" and disabled, and audit its attempted use for audit and incident response purposes. Also can script it out with cusrmgr.exe from the Windows 2000 resource kit. Z Edward E.
