Hi,

I have two collections of my servers and they have different maintenance windows. I update them every month normally but this time weird thing happened. All my servers were rebooted altogether regardless of their maintenance windows.

Now, how should I troubleshoot this scenario? How can I check on a specific server that in which MW was it when it was rebooted?

Hi,

I fell foul of this in a semi-production environment. I was of the opinion it would never reboot too, but it seems so patches do not honour the rules.

To find out the culprit, check the SYSTEM event log for event ID 1074. This will tell you which process triggered the reboot.

To find which patch is responsible check the Windowsupdate.log for the adverb "rebooting".

My lesson learn: test, test and test again.

Alright, I found the reason. There was another MW on All Windows Server Systems. It overlapped with my customized collections :(

So, how can I check that which computer is in which MW?

I am not sure without resorting to the logs of any affected machine. I found this general advice with some relevant comments that might help.

I guess I would remove the All Servers MW if you want to target specific servers in collections otherwise it will get over-complicated.

Do you deploy updates with SCCM? Have you configured your Windows Update Agent to "not configured" in Group Policy for all the Servers?
Do you have any deployments which bypasses the maintenace Windows?
