What are the services required for Active Directory replication?
You also know that the following systems and services are working:
- DNS infrastructure.
- Kerberos authentication protocol.
- Windows Time service (W32time)
- Remote procedure call (RPC)
- Network connectivity.
How do I replicate Active Directory sites?
A.
- Start the Microsoft Management Console (MMC) Active Directory Sites and Services snap-in.
- Expand the Sites branch to show the sites.
- Expand the site that contains the DCs.
- Expand the servers.
- Select the server you want to replicate to, and expand the server.
- Double-click NTDS Settings for the server.
What is a site and how replication works?
Sites ensure that replication is routed around network failures and offline domain controllers. The KCC runs at specified intervals to adjust the replication topology for changes that occur in AD DS, such as when new domain controllers are added and new sites are created.
What is site replication?
Our Replication feature allows you to quickly make an exact copy of your site in a new hosting environment. This functionality is very useful for testing as well as moving sites between staging and production.
How do you replicate two AD servers?
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.
How often do DCs replicate?
Intra-site replication: With the exception of critical directory updates that are replicated immediately, the source DC updates changes to its closest replication partner every 15 seconds. Inter-site replication: By default, the replication interval is 180 minutes and can be adjusted to be as low as 15 minutes.
What is the purpose of sites and services?
AD Sites and Services is the standard console for setting up and managing AD Sites (see Figure 4.31). Using the AD Sites and Services console, you can create and manage sites, subnets, site links, and site-link bridges.
What is the purpose of sites and services in AD configuration?
The information in Sites & Services is used by AD to create a replication topology, determine which DCs should authenticate clients, and help users connect to applications and services.
What is Istg in Active Directory?
Intersite Topology Generator (ISTG), which establishes connection objects between sites (only one Domain Controller in each Active Directory Site holds the ISTG role at any given time).
What is Active Directory replication topology?
Replication Topology is the route by which replication data travels throughout a network. Replication occurs between two domain controllers at a time. Over time, replication synchronizes information in Active Directory for an entire forest of domain controllers.
