Introduction
In this article I will create One Way Incoming Realm Trust for one side of a trust.
There are two types of trusts; the first one is a "Realm Trust" and the the other one is "Forest trust". Here we will create a Realm Trust.
Step 1
First of all open the Administrative Tools from the Start menu.
In the Administrative Tools Wizard a list of installed items will be available, here an option will be available named Active Directory Domains and Trusts, double-click on it to open it.
