Hi, In our company we have one domain and two active directory sites each site have two domain controllers. But the inter-site replication interval in every 180 minutes. Every day I am creating one or two new users from one site but the user is in another site. They are not able to login becasuse of this replication time. So everytime I am forcing replication manually. What is the best practice for normal inter-site replication interval time? We have around 1000 users in our domain. Thanks in advance.
