I have a NTP Server running on a Linux (Ubuntu 16.04) box and I also have to securely serve a bunch of Windows Server boxes (2012, 2012 R2 and 2008 R2 mainly). For network equipements and Linux servers I'm using MD5 keys but I don't know how to do something similar on Windows.
I tried to google that issue but all I could find is this thread.
How can I securely sync the Windows boxes with the Linux NTP server ?
Thank you.

https://serverfault.com/questions/740490/ntp-with-authentication-on-windows-system You need an AD domain server, the trust relationship between the AD server will be secure this will insure the SNTP connection is trusted. (SNTP is Windows NTP) – Ramhound – 2018-01-02T18:31:18.860
OK @Ramhound and what if I don't have an AD or don't want to set one. – dev93 – 2018-01-02T19:03:25.497
Read the link I provided. You said you had Windows Servers.... – Ramhound – 2018-01-02T19:18:32.190
The linked question on Server Fault discusses using the Windows boxes as the SNTP time source. It appears this question is about having the Windows servers get authenticated time from the NTP server running on Linux. – I say Reinstate Monica – 2018-01-02T19:36:20.760
Yes @TwistyImpersonator I already have a Linux box acting as an NTP server and I want windows clients to sync through it if possible. – dev93 – 2018-01-03T09:22:50.273
