I've built a server to provide time on the local network, and have been using it with Xen Server pools as I don't like giving the management interface on the hypervisor access the the outside network. There are currently no VLANs setup, and the time syncs as it should for the hypervisors. This NTP server is not a domain controller, secondary or otherwise (although I can change this if required, but would like to avoid having it as Primary).
The NTP server is a windows server 2008 R2 standard, with relevant services installed. I can go the linux route, but I'm not sure if would cause problems in provide time to windows systems (I don't imagine it would).
In any case, I've tested the configuration, and manually sync'd one windows system to it. What I want to do next is SYNC all the computers that are joined to the domain with this specific server. I have been unsucessful so far, I'm not sure if it's what I detailed in the GPO.
I essentially have the entry configured in the GPO:
Computer Configuration -> Administrative Templates -> System -> Windows Time Service -> Time Providers -> Windows NTP Configuration
This points to the server non-pdc-server.server_on_domain.ads
Should I instead have it point to the pdc and have the pdc somehow sync with this server? or use Windows NTP server instead of client? I'm a little confused.
