configure Windows Server 2016 to be an NTP server and also sync with external source

I've done a lot of Google searching to see how to set this up and tried many different things but none of them seem to be working.  Basically, I have 2 goals:

1. Setup Windows Server 2016 to be an NTP server  (should be able to test this by using telnet on port 123)
2. Have Windows Server sync with an external time source

I am using Windows Server 2016 in a domain environment and this server is the only domain controller (DC).  It is a virtual machine and I am using Vmware ESXi Hypervisor (version 6.5).  

I "think" I have the 2nd goal met but I can't seem to figure out the 1st goal.  The Windows firewall is turned off but I can't seem to telnet to port 123 on the server.

Here's some things I have tried:

1) Use Domain controller GPO

https://blogs.technet.microsoft.com/nepapfe/2013/03/01/its-simple-time-configuration-in-active-directory/ 

I did a GPUPDATE and also rebooted the server.  

2) Using W32tm

https://community.spiceworks.com/how_to/5765-configure-windows-server-to-query-an-external-ntp-server

w32tm /config /manualpeerlist:us.pool.ntp.org /syncfromflags:MANUAL

Stop-Service w32time
Start-Service w32time

w32tm.exe /resync /rediscover /nowait   --> I think this finally did the trick to meet Goal #2.  However, I'm actually seeing what's configured in the GPO, not what was configured with the W32TM command.

3) Registry hack

At least specify 2 servers for redundancy
Run all commands in elevated command prompt on PDC master server of root domain only

command would be:
w32tm /config /manualpeerlist:"servername1 servername2" /reliable:yes /update
net stop w32tm && net start w32tm
w32tm /query /source
w32tm /query /status

Open in new window


post that check system events on PDC server for event ID 35 and 37

You won't be able to use telnet to test, it is a UDP port.

Use a tool such as NTP Query Tool 1.2 for Windows
