    I read this on another site and thought and am just passing it along. Does anyone know if this is true or not?

    XP passwords rendered useless

    By Brian Livingston

    Windows XP, which has been marketed by Microsoft as "the most secure version ever," has been found to have a flaw so bone-headed that it renders passwords ineffective as a means of keeping people out of your PC.

    Reader Tony DeMartino alerted me to the problem, which all administrators of Windows XP machines should immediately take to heart:
    Anyone with a Windows 2000 CD can boot up a Windows XP box and start the Windows 2000 Recovery Console, a troubleshooting program.

    Windows XP then allows the visitor to operate as Administrator without a password, even if the Administrator account has a strong password.

    The visitor can also operate in any of the other user accounts that may be present on the XP machine, even if those accounts have passwords.

    Unbelievably, the visitor can copy files from the hard disk to a floppy disk or other removable media - something even an Administrator is normally prevented from doing when using the Recovery Console.
    This problem is unrelated to a feature of XP that allows an Administrator to set up automatic logon when the Recovery Console is used. Even without the Registry entry that enables this, XP is vulnerable. (For info on that feature, see support.microsoft.com/?scid=kb;en-us;312149.)

    Windows 2000, of course, doesn't allow Recovery Console users to access a hard drive without a password, if one previously existed.

    I notified four Microsoft executives of the XP flaw weeks ago, but haven't yet received an official response. There's no Knowledge Base article about it, and there may not even be a good solution to the problem.

    When I've spoken with Microsoft security pros about similar problems in the past, they've referred me to a company policy that says, "If a bad guy has unrestricted physical access to your computer, it's not your computer anymore."

    That's all well and good - but the fact remains that Windows 2000 doesn't allow anyone with an old CD to get password-free access, and Windows XP does.

    My recommendation: If you use XP machines in open spaces, put the PCs behind a locked door or put a lock on the PCs themselves. The bad guys know about this flaw, and it's just one more thing for the good guys to protect against.

    To send me more information about this, or to send me a tip on any other subject, e-mail me at Brian@BriansBuzz.com with "tip" in the subject

    IF a user has disabled the repair console password option in gpedit, THEN this applies not only to the Win2k boot but an XP CD boot as well, but ONLY if the user has disabled the recovery console password option.
    A lot of hype, not much fact, or he conveniently forgot that one little tidbit of VERY important information.

    But this
    is certainly true. For most any PC OS you can think of.

    For instance, if I can remove your hard drive and place it as the slave drive in another PC, I have now bypassed all your security.

    For instance, if I can load and run a high-end password crack program for long enough, I can get your password. May take 4 or 5 days or even a couple weeks but eventually a brute force attack will peel it out.

    I haven't had occasion to read this particular site but it looks like the fella who runs it is prone to being sorta careless with his writing.
