Eavesdropping the connection (MITM): Rerouting all IP packets to a certain machine makes it possible to eavesdrop on the connection by listening local network interface.And although blocking on DNS-level is pointless (using a different DNS server circumvents the blockage), it’s very easy to implement (as shown in this post) and is hence often used. social networks, political/religious content, pornography, piracy sites, etc.). Blocking sites: Especially in the last couple of years, many governments all over the world have used DNS forgery/spoofing to block access to various kind of Internet content (e.g.The two most prominent ones are to block access to a site or service, or to eavesdrop the connection using a man-in-the-middle attack (MITM). There are multiple reasons for wanting to reroute traffic. the connection is rerouted to a destination of your choice. In short, before you can connect to “”, you first need to know its IP address.Īnd because machines blindly connect to the IP address returned by the DNS server, being able to forge specific (or all) of its entries means that the client connects to a different server – i.e. Before a machine can connect to another machine and start the actual communication, a DNS request must resolve the name of the destination machine. Even though it sounds like a very simple task, this translation carries a great responsibility because it is an essential step to make communication between most machines even possible. Blocking content / Internet censorshipĭNS is responsible for managing the Internet’s namespace of domains by translating domain names into IP addresses. Verify the health of the domain controller by running the command dcdiag /v from the command line. Your system will be rebooted automatically for the changes to take effect.A prerequisites check will be done by Active Directory. It is recommended to stick to the default settings. Select the folder where your database, log files, and SYSVOL will be stored.For more information on NetBIOS name restrictions, see It is preferable to match the NetBIOS name with the root domain name. Since a DNS Server is being configured as part of our efforts, you’ll be warned that a delegation for this DNS server cannot be created.
Since this is the first domain controller, it automatically becomes the DNS server and also the Global Catalog (GC).Įnter a unique Active Directory Restore Mode password used to retrieve Active Directory data. Ensure that the domain functional level is equal to or higher than the forest functional leave.
Select the roles you want to install on this server.Else, close the server manager and retry. Make sure the IP address points to the selected server. Now, select the destination server on which the role will be installed.Else, choose Role-based or Feature-based installation. If you're going to deploy your DC in a virtual machine, choose Remote Desktop Services installation. You may read through it and click "next".
