Configuration and validation
Contents
DNS
It is necessary to make sure that the domains can solve the different DNS records, for that it is necessary to add conditional forwarders.
Parent domain
1. Open the DNS console and verify that a folder with the child domain name 1 is present.

2. Right-click Conditional Redirectors 1 and click New Conditional Redirector … 2 .

3. Enter the DNS name 1 , add the IP address of the child domain controller 2 and click OK 3 .

4. The redirector is added to link to the child domain 1 .

Child domain
Do the same thing on the child controller with the parent domain.

Active Directory Sites and Services
On the parent domain, open the console and check that in the site created 1 , in the folder Server 2 is the domain control 3 and the replication link 4 .

Group Strategy
It is possible in the console to display the group policies of the other domains of the forest and to link them to another.
1. From the console, right click on Domain 1 and click on Show domains 2 .

2. Choose the domains to display 1 > and click OK 2 .

3. Both domains are manageable in console 1 .

Active Directory Domains and Trusts
1. On the parent controller open the console and verify that there is a link between the two domains (presence in the console) 1 .

2. (optional) Open the properties of each domain and validate the Parent / Child link.
FSMO Roles
1. On the child domain control (NY), open a command window and enter the following command:netdom query fsmo
2. It can be seen that 3 roles are carried on the DC of the child domain and the other two on the DC of the parent domain, which is normal because two FSMO roles are unique in the AD forest.
