!!! Overview
[{$pagename}] is a [Authentication Mechanism] used in the [Windows Client Authentication Architecture] which verifies logon requests, and it registers, [authenticates], and locates [Domain Controllers]. 


[{$pagename}] can only be used after user, service, or computer [authentication] has taken place. During network logon, the process does not use the [credentials] entry dialog boxes to collect data. Instead, previously established credentials or another method to collect credentials is used. This process confirms the user's identity to any network service that the user is attempting to access. This process is typically invisible to the user unless alternate credentials have to be provided.

To provide this [Authentication Mechanism], the security system includes these authentication mechanisms:
* [Kerberos] version 5 protocol
* [Public Key] [certificates]
* [Secure Socket Layer]/[Transport Layer Security] ([SSL]/[TLS])
* [Digest SSP]
* [NTLM], for compatibility with [Windows Server NT] 4.0-based systems
* [Netlogon Remote Protocol]
