Finding the Domain Controller Using Active Directory
The Windows interface method involves using Active Directory. The active directory is the Central Manager of a Microsoft network. Among the controls that is has are users and computers. In a Microsoft network, one does not enter the domain without first getting clearance from the active directory. In that capacity, a user is added to the domain before entering. Likewise this happens to the computers that are in the domain.
One of the domain computers is the domain controller. So to find the domain controller, you can use active directory. Step one, open Active Directory Users and Computers. To open Active Directory Users and Computers, click Start, click Control Panel, double-click Administrative Tools, and then double-click Active Directory Users and Computers.
Next in the console tree, right-click any node or folder, and then click Find. Use this method if you don't know where the domain controller is located. On the other hand, if you know which folder contains the domain controller, right-click that folder to narrow the search to that folder. However, In Find, click Computers and in Role, click Domain Controller.
If you do not know which folder contains the domain controller, in In, click the domain you want to search or click Entire Directory and click Find Now.

A caveat is important here. Usually, only the administrator is allowed access to the Active Directory. Ordinary users, however, can access the active directory. The administrator rights are not necessary.
