To perform offline critical updates on CKDC1 without rebooting the server, you should stop
the Active Directory domain services and install the updates. Start the Active Directory
domain services after installing the updates.
By stopping the Active Directory domain services, you don’t need to reboot the server.
The updates are related to the Windows Server 2008 on CKDC1 so when you stop the
Active Directory domain services and start it again after the installation of the updates, the
Server will perform in a normal way.
