What are inter site transports?
The Inter-Site Transports container provides the means for mapping site links to the transport that the link uses. When you create a site link object in the respective Inter-Site Transports container, AD DS uses RPC over IP to transfer both intersite and intrasite replication between domain controllers.
What are AD DS sites and site links?
Site link. Site links are Active Directory objects that represent logical paths that the KCC uses to establish a connection for Active Directory replication. A site link object represents a set of sites that can communicate at uniform cost through a specified intersite transport.
What is Intrasite replication?
Intrasite replication occurs between DCs within a site. The KCC automatically creates replication connections between DCs within the site. The ring topology created by the KCC defines the path through which changes flow within the site.

On what protocol AD replication works across the site?
Active Directory replication uses Remote Procedure Call (RPC) over IP for replication within a site. RPC is an industry standard protocol for client/server communications that is compatible with most types of networks. For replication within a site, RPC provides uniform, high-speed connectivity.

How do I run KCC?
Solution
- Open the Active Directory Sites and Services snap-in.
- In the left pane, browse to the NTDS Settings object for the server you want to trigger the KCC for.
- Right-click on NTDS Settings , select All Tasks, and Check Replication Topology.
- Click OK.
What is subnet in Active Directory Sites and Services?
Subnets – Subnets are the IP ranges that are associated with specific AD sites. DCs and clients use the subnets you define to determine what site they are in.
What is Sites in Active Directory?
Sites are a location in a network that holds AD servers. A site is defined as one or more subnets. Site Links. View AD site links across your forests. Site links represent a set of sites that can communicate at uniform cost through some intersite transport.
What is bridgehead server in AD?
A bridgehead server is a domain controller (DC) that functions as the primary route of Active Directory (AD) replication data moving into and out of sites. Therefore, if you have DCs from multiple domains in each of your sites, you’ll need multiple bridgehead servers to transport each domain’s replication traffic.
What is the Inter Site Topology Generator?
The intersite topology generator is an Active Directory process that defines the replication between sites on a network. It runs the KCC to determine the replication topology and resultant connection objects that the bridgehead servers can use to communicate with bridgehead servers of other sites.
How do you replicate DC and ADC?
Solution
- Open the Active Directory Sites and Services snap-in.
- Browse to the NTDS Setting object for the domain controller you want to replicate to.
- In the right pane, right-click on the connection object to the domain controller you want to replicate from and select Replicate Now.
What is the inter-site transports container for?
The Inter-Site Transports container provides the means for mapping site links to the transport that the link uses.
How do I create a site link object using SMTP?
When you create a site link object, you create it in either the IP container, which associates the site link with the remote procedure call (RPC) over IP transport, or the Simple Mail Transfer Protocol (SMTP) container, which associates the site link with the SMTP transport.
How is Intersite replication traffic sent between sites?
Replication traffic between sites is always sent from a bridgehead server in one site to a bridgehead server in another site. Although it is the job of the ISTG to generate the intersite replication topology and designate bridgehead servers, you can manually designate bridgehead servers as well.
How can SMTP be used to replicate information between domain controllers?
First, SMTP can be used only to replicate information between domain controllers in different domains because the domain directory partition cannot be replicated using SMTP—only the configuration, schema, and global catalog directory partitions can be replicated.
