When a domain administrator resets a user's password and then logs on to their Windows 2000-based computer with the reset password, the administrator can access the user's secured private e-mail and browser data. Additionally, if the computer is left unattended, anyone with access to the computer may also be able to see the user's private data.
The Windows 2000 implementation of Microsoft Cryptography Service Providers (CSPs) permits users to store their decryption keys on their computers that are protected with their domain password.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows 2000 Service Pack 4.
After installing this hotfix, the administrator can set a policy enforce strong password protection on user's computer. After the policy has propagated, the user has to type a password when he or she first accesses the encryption key. The key is cached for subsequent uses until the end of a fixed time-out period. After the time-out period has expired, the key expires and the memory that held the key is cleared to subsequent recovery.
With the strong password protection feature, the domain administrator cannot gain access to a user's private information. The strong password protection feature prevents a separate password from accessing the user’s private decryption key.
