Server is automatically rebooting

One of my servers is logging everyone out and rebooting. There is no option to postpone. It is part of my Dynamic Group server test group, but that group is set to "Deploy during business hours(Do not reboot)".

Why would the server be ignoring the deployment policy and forcing a reboot?
