I'm running a Windows Server 2008, SP1 configured as a DC?
I would like to know if I can apply a restrict option to all hosts that are not authorized to perform NTP queries to deny NTP query requests from clients not authorized.
There is any idea about the configuration we have to do?

    By default ,all servers and computers members of the domain synchronize time from a domain controller. It's recommended to keep this configuration for all machines joined to this domain.
    If you want block all unauthorized machine to synchronize time from this server , it can be done through windows firewall by blocking the port 123 UDP used for time synchronization.
