Hello Roger Roger,
Thank you for posting in Q&A forum.
Are all the domain controllers in the same site?
It seems they are in different sites. You can use command repadmin /syncall /AdeP to replicate changes to other domain controllers.
This can be useful for forcing immediate replication across all domain controllers in an AD forest.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
