SCCM server reboot issue

Question

Hello,

I am hoping that someone can assist me in diagnosing why our server did not reboot during the maintenance window. The server in question was stuck and had to be manually restarted. Here is the information from the RebootCoordinator.log:

Not sure why the server did not fully reboot. All of our servers are set to reboot after installing updates during the maintenance window.

Thanks in advance.

Answer 1

The log says" The client is instructed to disallow server sku reboots."

Answer 2

Anything on servicewindow manager log? Also, what do wuahandler and updatesdeployment logs say?

Answer 3

Hi @PB_JBergener ,

Could we know if we check the option of suppress the system restart on servers or workstations? If so, the client could not be restarted during the maintenance window.

Besides, if the operation of reboot is normal, we could see the following the screenshot, please refer to it:
