This is one of those really basic tasks you can easily set up with no added software or even Powershell scripts. It’s extremely useful too. Say you need to reboot a server because you installed some software that you didn’t expect needed a reboot, or there’s some updates, or some other reason. You can’t really do it until after hours and you don’t want to hang around and would just like it to reboot itself a couple of hours after closing time when everyone is home.
You might also want to reboot a Windows Server a month or once a week as a matter of routine maintenance.
This is fairly trivial to set up in Task Scheduler.
How To Schedule A Windows Server For Automatic Reboot
Note: I’m using Server 2016. This is almost exactly the same in 2008 and 2012.
Step 1 – Open Task Scheduler. In the newer versions of Windows Server you can just click on the start button and type “Task Scheduler”. You can find it manually under Control Panel under Administrative Tools. You can find it in the Start Menu in Server 2003 but the Task Scheduler is a bit different.
Step 2 – Right Click on the Task Scheduler Library (Highlighted in the picture in Step 1) and click “Create Basic Task”. This will open the Wizard. You don’t have to use the Wizard, but since this is a very simple task it’s easier.
Step 3 – Give a name to the task. I called this “Restart Server Once”. In a multi-server environment, my personal preference is to call it “Restart This Server Once” or “Restart Local Server Once” to show that the task restarts that specific machine. As I usually also have tasks to restart remote servers and workstations on at least one of them as well. If I were also making one to restart the box on a schedule I’d name it something like, “Restart Local Server On First Of Month”.
Step 4 – Since this task is to just restart the server one time click the “One Time” option and then click next.
You’ll note the sub-task called “One Time” under triggers.
Step 5 – Give it a date and time to restart. Click next.
I chose 8pm the next day.
Step 6 – Select “Start A Program”. Click Next.
Step 7 – Type “shutdown” without the quotes into the “Program/Script” box and “/r” into the “Add arguments” box. Click Next.
Step 8 – Click Finish
Step 9 – You aren’t done yet because you want this to run if you get logged off and you want to set this up so you can use it again later. In the Task Scheduler right-click on your new task and click Properties. This will bring up the general settings page. The radio buttons on the bottom will default to “Run only when user is logged on” change it to “Run whether user is logged on or not”.
Step 10 – Click OK. It will make you enter your administrator password.
Changing the Schedule for The Automatic Reboot
So now you have a task that will automatically reboot your server (Or PC) one time. Now you need it to do it again. There’s no need to make another task, you just need to update the trigger.
Step 1 – Go back into Task Scheduler, right-click on your task and click Properties. Click on the Triggers tab.
Step 2 – Click on the “One Time” trigger and click the Edit button. Change the time and date, click OK on all the dialog boxes and your server/PC will now restart at the new time.
It will ask you to re-enter the administrator password.
