Windows Logon Availability

Applies To: Windows Server 2008

Windows logon availability determines whether the Windows logon process is able to be completed successfully. The logon process is the interface between the account for a user, process, or service and the computer that establishes authenticated credentials for the account and allocates the appropriate system and network resources. Windows logon manages the use of the secure attention key (CTRL-ALT-DELETE) to initiate the login screen, load the user profile on logon, and lock the computer.
