Darshan I didn't understand what do you mean Child AD. Are you referring to another domain controller from different site or a DC part of child domain.<br />
<br />
I assume that you are talking about additional DC, so make sure VPN tunnel configured correct, like site-to-site configuration is correct. As Will mentioned reduce replication interval to 15 minutes. Also if DCs are in different subnets, then make sure these subnets are configured properly over firewall.<br />

Hi All,<br />
<br />
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. <br />
<br />
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.<br />
<br />
Thanks and Regards<br />

Active Directory Design - Syncing new site very slow

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
