Users can configure Windows to enter or not a sleep or hibernation mode and, therefore, prevent a Domain or E3 Server in execution from becoming inaccessible. This is performed by using the Prevent Windows from entering sleep/hibernate state option. The available options are 0: Never prevents Windows from entering sleep mode, 1: Prevents Windows from entering sleep mode if a Domain is executing (default), and 2: Prevents Windows from entering sleep mode if an E3 Server is executing.
