Using domain network server to host NTP service for other, non domain network segment
I have a Windows Server 2008 R2 DC which part of our AD domain. I also have a separate network that is independent and gets no internet access. However I would like the computers on that independent network to get accurate time synchronization.
How can I configure an NTP server on my DC and point the computers on the independent network to the NTP server? The DC has another NIC available that is not being used which I could plug into this independent network.
Is this even possible on a DC which is already doing Windows Time Service? Will it break the internal time synchronization for all my domain computers? Or should I create an NTP server on another domain computer/server?
I've tried doing some searching online but I must not be phrasing my searches right because I can't find an answer. I'm hoping someone with good knowledge in this area can help. Thanks!
