Caching of logon credentials must be limited.

Description
The default Windows configuration caches the last logon credentials for users who log on interactively to a system. This feature is provided for system availability reasons, such as the user's machine being disconnected from the network or domain controllers being unavailable. Even though the credential cache is well-protected, storing encrypted copies of users' passwords on workstations does not always have the same physical protection required for domain controllers. If a workstation is attacked, an unauthorized individual may isolate the password to a domain user account using a password-cracking program and gain access to the domain.
