I have stood up a Windows Server 2012 R2 server to act as a replacement Domain Controller for an old Windows 2008 server in an enclave domain I support. I'm taking my sweet time in demoting the old one because I want to minimize anything I might have missed, and one of the things I was asked about was whether the new server was ready to take over as the NTP server. Logging in to a couple of production servers in this domain and running "w32tm /query /source", sure enough they're still spitting back the old DC server name.
I figured it would be a quick and easy process to see where they're getting this information from and update it, but for the life of me I cannot find where they are getting their NTP source information from! I assumed it would be something in DNS, or a Role/Feature I needed to install, or maybe Group Policy, but everywhere I look I can't find where this setting is and I can't imagine it'd be as complicated to update as having to log in to every server and make a registry change?
I'm going to keep poking around on Google to see if I can suss this out, but in the meantime I figured I'd ask the smart kids in the class... how do I roll out a new NTP server for my domain and have all the clients recognize it as the new Source?
