How-To Configure Windows Server 2019 as the NTP server via Group Policy

In this video, I demonstrate how to deploy an NTP server and attach host machines as NTP clients to poll time from the server.

On the NTP Server GPO:
To do this, create a new GPO and assign it to the OU with computers. In the GPO Editor go to the following section Computer Configuration - Administrative Templates - System - Windows Time Service - Time Providers and enable the policy Enable Windows NTP Server.

On the NTP Client GPO:
To do this, create a new GPO and assign it to the OU with computers. In the GPO Editor go to the following section Computer Configuration - Administrative Templates - System - Windows Time Service - Time Providers and enable the policy Configure Windows NTP Client.

Also Enable Windows NTP Client in the Client GPO policy you create

Below are the flags you can set to
0x01 SpecialInterval
0x02 UseAsFallbackOnly
0x04 SymmatricActive
0x08 Client
