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
I did a GPUPDATE and also rebooted the server.
2) Using W32tm
w32tm /config /manualpeerlist:us.pool.nt
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
