I have a requirement as follows;

The information system uses replay resistant authentication mechanisms for network access to non-privileged and privileged accounts.

    I need the mechanisms and the supporting Microsoft page the validates the replay resistant aspects of Windows 2008.  I know Kerberos is in effect, but you still have a (configurable) window.  I know each user has a SID and each computer has a SID, but is the computer SID used in the process?  I am open to other considerations.

The guidance states;

An authentication process resists replay attacks if it is impractical to achieve a successful authentication by recording and replaying a previous authentication message. Techniques used to address this include protocols that use nonces or challenges (e.g., TLS), and time synchronous or challenge-response one-time authenticators.

Kerberos is the default authentication method and you are protected against replay attacks

...Note that since all authenticators must be unique, they are valid one time only. Therefore, Kerberos protects the system from replay attacks.....
