     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.
     ...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....

Later in the same article, Brian correctly points out that this exploit
requires physical access to a PC; and that if a hacker has physical
access to your PC, then they can eventually break in, if they're good.
But this "use the W2K CD" trick makes breaking in trivially fast and
easy, and it shouldn't be that way: It's a major gaff. Someone's head
should be on a post over at Microsoft, for this.
BTW, "Brain's Buzz" is a new publication. You may recognize Brian
Livingston's name from any of his many authoritative books on Windows
(see  
http://www.tinyurl.com/615r ), from his long-running InfoWorld
columns, or from his speaking at trade shows and in the media: He's
very, very good at what he does.
Along with Brian's Buzz, he's also created a specialized search engine
for researching Windows problems. With one "WinFind" search, you can
simultaneously comb the web sites of Annoyances.org, JSI, Inc., the
Langa List (Standard Edition), Lockergnome, PCWorld.com, Tom's
Hardware,  Windows 2000FAQ, Windows Web Solutions, WinInformant,
WinNetMag, WinSupersite, Woody's Watch, and several of Brian's own
resources.
WinFind's full search is available at 
http://www.briansbuzz.com/search/,
and the simple search is on the front page at

.. Both WinFind and the Brian's Buzz newsletter are free. Check 'em out!
