Hi All, 

I am sure this question is answered before but I couldn't end up in right direction. We manage patching using SCCM and there is no issue in deploying patches. In recent times when servers are not rebooted on particular time period it prompts for Restart option when I login. So I had to postpone restart from the drop down. I understand SCCM manages has policies to suppress client restart i.e. both server and workstation and I have enabled this policy. 

My question, is there a way I can disable this prompts? 

Thanks for your help! 

Cheers

Prabhu

The Windows Update Agent is often responsible for rebooting systems outside of ConfigMgr's control which is discussed at the link posted by Prashant.

Thanks Prashant, I have checked GPO settings and its not configured to work with windows update and so I believe it gets only SCCM policy to reboot. This happening on server side and good part its not restarting but prompts when we establish remote desktop connection. Is this kind of bug?

have you suppressed display notification as well?

Yes I have enabled that option.

good...what settings have been setup locally on the system for Windows Update?

It doesn't matter whether it is configured or not. By default, unless you've explicitly disabled the WUA, the WUA *will* reboot systems at 3AM that have any reboots pending and *will* display it's own reboot prompt.
