We have a AD infra with around 10000 user account and 20000 computer accounts. We have a Primary AD at head office and Child AD at each location which are remote sites having MPLS or VPN tunnels configured to sync with Primary AD.
Our issue is when we add more remotes sites and setup an Child AD the syncing between the Primary AD and Child AD take a long time. Is there any way to make it fast or is there any other design for AD with multiple remote sites.
Thanks and Regards
