QUOTE: Attackers may have had an easier time cracking the Muvico.com Web server because it is running Windows 2000, said Rich Miller, an analyst at Web tracking company Netcraft Ltd. Windows 2000 is an older version of Microsoft Corp.'s operating system, and it has been the subject of frequent widespread attacks, including last year's Zotob virus.   "Microsoft still supports Windows 2000 to the extent that if you're current, you should be well-protected. But it is less secure than Windows Server 2003," Miller said. Still, there remain a "substantial number of Web sites that continue to run on Windows 2000," he said.
