Creating One Way Incoming Forest Trust For Both Side of Trust

Introduction

In this article I will create a one-way incoming Forest Trust for both sides of a trust.

There are two types of trust, the first one is "Realm Trust" and the other one is "Forest Trust", here we will create a Forest 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.

Now the Active Directory Domains and Trust Wizard will be opened, the Domain Node will be available on the left hand side in the ADDT Pane.

Step 2

Right-click on the Domain Node and click on it's Properties.

Now the Property Window will be opened, here by default the General tab will be open.

Step 3

Click on the "Trusts" Tab available beside the General Tab and after that click on the "New Trust" Tab.

Now the New Trust Wizard will be opened, first some information about the Trust will be provided, click on the "Next" Tab to start adding the trust.

Step 4

On the next page provide the name for the trust and then click on the "Next" button.

The next page is for the "Trust Type". Two options will be available, one named "External Trus"t and other named "Forest Trust". But remember one thing that you will get a Forest Trust only when, in the "Name of Trust", you provided the name of the domain of your system otherwise this option will not be available to you.

Among these two options select the Forest Trust and then click on the "Next" Button.

Step 5

The next page will ask you for the Direction of the trust, select the second option named "One Way Incoming".

The next page is for the "Side of Trust", here select the second option, in other words "Both this Domain and the Specified Domain".

Step 6

On the next page you need to provide the name and password for the user that has Administrative Privileges in the specified domain.

Finally it will ask you for confirmation of creating the trust, so click on the "Finish" button to create the trust.
