I'm confused on this.
For years we've set up deployments with deadlines, say 8PM.
The deployment option to ignore MW is not enabled. So the updates should only install at the deadline.
We have MW that have lined up with the deadlines, 7:50PM to 10PM.
This has worked flawlessly for us for years, or so we thought.
Now, we've introduced new business sensitive servers to the patch windows.
What someone noticed is that the updates are actually starting to install at the beginning of the MW, 7:50PM, and not at the deadline for the deployment, 8PM.
I never noticed this. No one ever mentioned it before, but this was noticed that the updates were installing and rebooting, albeit, minutes before the deadline was to begin on the new servers.
Review of the logs surely shows that the updates are beginning to install at the start of the MW, not the deadline.
I know I can change the MW to begin at 8PM, but why is this happening?
We only ever have 1 deployment. We just update it with new updates every month.
I am wondering if the Software Updates Client Agent Update Installation tab has something to do with this.
I don't understand the setting "Enforce all mandatory deployments"
We have this configured for 1 day. Not even sure why I have this enabled.
I've read the help on it but do not understand.
Is this causing the updates to begin installing at the beginning of the MW, before the deadline of the deployment?
