|Message:||Time Provider NtpClient: This machine is configured to use the domain hierarchy to
determine its time source, but it is the PDC emulator for the domain
at the root of the forest, so there is no machine above it in the
domain hierarchy to use as a time source. It is recommended that you either
configure a reliable time service in the root domain, or manually configure
the PDC to synchronize with an external time source. Otherwise, this machine will
function as the authoritative time source in the domain hierarchy. If an external
time source is not configured or used for this computer, you may choose to disable

This event is often logged when a new forest is created following the promotion of the first domain controller (DC). It is also logged when the PDC emulator role is seized or transferred to another DC.
Do one or more of the following:
