Configuring Active Directory Sites And Services Subnets Best Practices

An effective network will have both a physical and logical topology. Network topology, hardware locations, and IP address assignments all make up the “physical topology,” which is a metaphor for the network’s overall structure. The logical topology of a network or service defines the limits of its security. The Domain is the logical topology in an Active Directory infrastructure, while Sites and Subnets are the physical topology.

What are active directory sites and services?

Directory ServiceActive Directory sites, area trees, area controllers, subnets, and intersite links can all be managed through the Sites and Services console in the Microsoft Windows System. Including new components at an existing site, such as servers, area controllers, links, and subnets. Transferring and fixing local controllers.

A site is any given geographical location or interconnected set of computers. It can be in a different building, city, or even country. The setup and configuration of sites and subnets are presented here as an illustration. Site A and Site B will be set up, and the appropriate servers and subnets will be allocated to them.

The desired setting will consist of the following:

The demo’s SRV1 server is physically located in a different city, in the Branch office. A 256kb link joins it to the main domain. The present configuration uses the factory-installed AD site.

AD Sites and Services – Subnetting best practices

1) Do nothing and see what happens?
The remote computers in each subnet could be connected to the closest data center, so AD-aware packages like logons must be routed to the closest DCs, DFS shares, and place-aware systems. It isn’t always practical to put data centers there.

Create a couple of new websites, such as
Site One Remote VPN Access Points with a 50 Mbps Connection
The site is called “Remote VPN Access Points in the Neighborhood of Site One That Have Cellular Internet.”
Then, forward the subnets of all the minor websites to their new home pages. And only leave the datacenter’s internal subnets linked to the datacenter’s website, for instance? This, along with the price cost, should be sufficient to let AD know whether the customer is in a nearby location with a fast or slow connection. Since there are no servers in those outlying, small locations, I get that replication isn’t always a factor.

Thirdly, create one hundred or more new websites, one for each physical location.
I’m starting to doubt that there will be any positive effects from doing this.

Using active directory sites and services

Making a new page and setting up page-level replication
Setting up licenses and items in the listing service (DS) web interface
Improving a website by including servers, area controllers, intersite links, and subnets
Field controller relocation and maintenance
