Upgrading Windows Server 2012 to 2016 Removes Time Server Role

If you’re using a Windows Server 2012 or 2012 R2 server as a Time Server for your organization, you’re better off just doing a clean installation of Windows Server 2016 instead of the in-place upgrade.

According to KB4051628

After you do an in-place upgrade on the computer to install Windows Server 2016 Version 1607, the computer is no longer advertised as a time server.

There’s actually a pretty easy fix. The upgrade simply doesn’t set a registry value during installation.

Per the same KB article:

Locate the following registry path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer

Set the DWORD value of Enabled to 1.
