I have a question for other experts out there.
Guidance states a PDCE in a child domain should point to any DC in the forest root to maintain domheir (preferably the PDCe in the forest root).
The GPO value format in the NTP server setting is "(FQDN | IP),server-flag"
If I want to automate this as much as possible for _my_ PDC's time policy, I *should* be able to use the _pdc SRV record for the Forest root's PDC emulator in place of the A record FQDN, allowing the child domains PDCe to find the PDCe role holder in the forest root...
Has anyone tried it?
