PC or Server is not getting shutdown on standby mode.
If your Windows computer is on standby at the time for which a shutdown is scheduled, the shutdown starts after standby mode ends. This is true even if the time scheduled for the shutdown (through the Shutdown Schedule command) has already passed. For example, if a shutdown is scheduled for 7 p.m. to 7 a.m., and your computer is on standby at 7 p.m., it will not shut down at that time. But if the computer resumes normal operation at 9 p.m., the shutdown begins then. The notification will indicate that an administrative shutdown began at 7 p.m., and a minute later the computer will shut down. The computer will turn on again twelve hours later
