Activity 10-2: Demoting a Domain Controller to a Member Server
Time Required: 30 minutes
Objective: Demote a domain controller to a member server.
Description: Some of the following activities require a domain controller in a new forest. In this
activity, you demote Server1XX to a member server and in the next activity, you install AD DS
again as a new DC in a new forest.
Remember to replace XX with your student number in these steps.
1. Log on to Server1XX as Administrator.
2. Click Start , type dcpromo in the Start Search text box, and press Enter to start the Active
Directory Domain Services Installation Wizard. Click Next in the welcome window.
3. In the Delete the Domain window, make sure the Delete the domain check box is selected,
and then click Next .
4. If you see the Remove DNS Delegation window, click Next . In the Windows Security window,
type Administrator and Password01 in the corresponding text boxes, and then click OK .
5. In the Administrator Password window, type Password02 in the Password and Confirm
password text boxes. Note that you're using the password to log on to the local computer
because this server is no longer a domain controller. Click Next .
6. In the Summary window, verify your selections. Note that the server will become a member
server after the process is finished. Click Next .
7. If you see a message stating that the DNS delegations couldn't be removed, click OK . When the
wizard is completed, click Finish . When prompted to restart the computer, click Restart Now .
8. After your computer restarts, log on to the domain as Administrator with w2k8adXX\
administrator as the username and Password01 as the password, and then open Server Manager.
9. In the left pane of Server Manager, click the Roles node, and in the right pane, click Remove
Roles . When the Remove Roles Wizard starts, click Next in the welcome window.
10. Click to clear the Active Directory Domain Services check box, and then click Next . In the
Confirm Removal Selections window, click Remove . After the removal is finished, click
Close . When prompted to restart, click Yes .
11. After the computer restarts, log on to the domain from Server1XX as Administrator (following
the procedure in Step 8). The removal of Active Directory Domain Services continues. When it's
finished, click Close .
12. Next, you should remove the DNS Server role. Because Server1XX is no longer a domain
controller, DNS doesn't contain Active Directory-integrated zones. Click Remove Roles , and
then click Next .
13. Click to clear the DNS Server check box, and then click Next . Click Remove . When the
removal is finished, click Close . When prompted to restart, click Yes .
14. After the computer restarts, log on to the domain from Server1XX as Administrator (again,
following the procedure in Step 8). The removal of DNS Server continues. After it's finished,
click Close .
15. Stay logged on, and leave Server Manager open for the next activity.
