What is the Autologon utility and how does it work?
This solution applies to all versions of Symantec Endpoint Encryption Full Disk and GuardianEdge Hard Disk.
Autologon is used by Policy Administrators for remotely deploying software to computers protected by GuardianEdge Hard Disk. Many software installation packages require one or more restarts of the target computer, and Autologon will automatically authenticate without user or administrator intervention. The Policy Administrator defines a window of time during which Autologon remains active, along with the total number of restarts that may occur within the defined period.
When either the total number of restarts has been reached, the defined time window has elapsed, or the computer shuts down for more than five minutes, the Autologon feature terminates. Once Autologon initiated by a given Hard Disk Computer Policy Logon GPO has terminated, subsequent invocations of the Autologon feature require that you either update the existing GPO and select new Autologon settings or create a new Hard Disk Computer Policy Logon GPO with the desired settings.
The Autologon policy will take effect approximately five minutes after receipt.
Because this policy temporarily bypasses the normal logon process for Symantec Endpoint Encryption Full Disk or GuardianEdge Hard Disk, computers receiving this policy will be in a state of heightened vulnerability while Autologon remains active. To minimize the associated risks, make certain that you carefully review the number of reboots allowed and the inclusive dates and times that Autologon will remain active before linking a GPO containing this policy.
More information on the implementation of the Autologon utility can be found in the SEE-FD/GEHD Policy Administrator Guide.
