Hi Team, Just curious to know about the meaning and the event of occurance for the statement: "CRebootCoordinator:Reboot Coordinator received a SERVICEWINDOWEVENT DELETE Event" in Reboot Coordinator.log. We have a machine that rebooted automatically after installing a patch, though the service window (MW) for the machine is set in such a way that it has been set to far future, that means though the machine will inform the user that machine is pending for reboot and need a manual intervention to get it rebooted. When we check the logs from the problematic machine we found that we are getting above statement. Can you please tell when and why thus occurs. Also we have check and the problematic machine is not sharing multiple MW. Any Help would be appreciated. ThanksModassir Khan

Ensure that the "Allow system restart outside of maintenance windows" is not selected in the Schedule tab of the advertisment properties.

Are you sure the machines problematic or the user?
