Automatic Update setting inconsistent across farm servers (SharePoint Server 2016)
APPLIES TO: 2013 2016 2019 Subscription Edition SharePoint in Microsoft 365.
Rule Name: Automatic update setting inconsistent across farm servers.
Summary: Servers in the SharePoint farm do not have the same Automatic Update settings configured.
Cause: One or more servers in the farm have update settings that are different from the other servers in the farm.
Resolution: Ensure all servers in the farm have the same update settings
Verify that you are a member of the Administrators group on the local computer.
In Control Panel, click System and Security, and then under Windows Update, click Turn automatic updating on or off.
On the Choose your Windows Update settings page, make sure that the update settings are the same as other servers in your farm. Change the update settings if needed.
If you can't change the update settings, the update settings may be locked in group policy. If this is the case, ensure the same group policy is being applied to other servers in the farm.
