How to know if your computer is locally controlled or externally controlled? A domain controller is a domain controller, which is a server that is used to manage users, computers, and resources in a network. Domain controllers can be divided into local domain controllers and external domain controllers, local domain controllers refer to domain controllers in the same LAN as computers, and external domain controllers refer to domain controllers that are not in the same LAN as computers. There are several ways to determine whether a computer is controlled locally or externally:
Method 1: Use a command-line tool.
Open the Start menu, type cmd, press Enter, and open a command-line window.
Enter ipconfig all and press Enter to view the details of the network adapter.
In the "DNS Server" column, check the IP address of the domain controller, if it is a local domain controller, then the IP address should be in the same network segment as the IP address of the computer, for example, 192168.1.x；If it is an external domain controller, the IP address and the IP address of the computer should not be in the same network segment, for example, 100.0.x。
In the "Primary DNS Suffix" column, check the domain name of the domain controller, if it is a local domain control, then the domain name should be the same as the domain name of the computer, for examplecom；If it is controlled by a foreign region, the domain name should be inconsistent with the domain name of the computer, for examplenet。
Method 2: Use system tools.
Open Control Panel, select System and Security, and then select System.
In the "Computer Name, Domain, and Workgroup Settings" column, check the domain information of the computer, if it is a local domain control, then the domain name should be the same as the domain name of the computer, for examplecom；If it is controlled by a foreign region, the domain name should be inconsistent with the domain name of the computer, for examplenet。
Click "Change Settings", and in the pop-up window, select the "Network ID" button to launch the "Join Domain or Workgroup Wizard".
On the second page of the wizard, look at the location of the domain controller, and if it is local, the location should appear as Local Network;If it is an out-of-town location, the location should be displayed as "Internet" or "Other Network".
