Instructions and Help about Are Form 8453 S Authenticate

Welcome to the next free video in the Active Directory training course. In the last video, I looked at how to create sites and subnets. In this video, I will look at how these sites can be configured to replicate Active Directory traffic in an efficient way that matches the current state of your network. First of all, I will start with just the New York site. In this particular case, let's say the New York site has seven domain controllers in it. If the client were to log into the network, they would be authenticated by one of the domain controllers. If the user then changed their password and logged off and logged on a second time, they would be authenticated by a different domain controller. For this reason, you want replication within a site to happen quickly. This type of replication is called intra-site replication. Intra-site replication is replication that happens between domain controllers in the one site. You will be happy to know that Active Directory handles this kind of replication without any configuration. It does this by connecting all the domain controllers in that site together in a ring. You can see that the seven domain controllers are each connected to two other domain controllers. This gives some redundancy and also reduces the number of connections required in sites with a large number of domain controllers. In Windows Server 2003 and above, intra-site replication will start 15 seconds after a change has been made on a domain controller. With such a small delay, all domain controllers on this network will receive the change in less than a minute. If the number of domain controllers on this network were increased to 8, the delay for a change to replicate to each domain controller starts to increase. Each...
