Description:
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  the NtpClient.
