Server reboots after Windows Update

Steel Contributor

I have 8 servers all running Windows 2016. I have 3 of the servers that will automatically reboot after the Windows Updates complete. The other 5 servers always show "waiting to restart outside of active hours", but they never restart after active hours. I have everything setup in Group Policy so not sure why 3 of the 8 servers reboot and the other 5 never reboot. Where can I look to see what is causing the discrepencies? Thank you for any help.

Do I look in the registry of each individual server or just my domain controller where I have the Group Policy setup?

I'd compare the settings of two different acting members.

I checked all servers and they all have the same registry settings
