Replicating information in AD

Question

I have an AD at Headquarters and an AD at Branch, and everything I update or add to one isn't replicating to the other.

with this users are not able to access folders on the server.

To add information in AD in the Matrix I use Active Directory by Windows 10, because in the Server the AD shows that it doesn't have any items to display, in the Branch Server the AD shows all the available items, groups, users etc.

If you can help me please.

Answer 1

I'd check the required ports are flowing between the networks.
