How to demote current Domain Controllers to member servers and uninstall DNS

Note: Important: Prior to demoting domain controllers make certain that the replication process
from the old domain controllers to the new domain controllers has completed. Check the directory
service with the event viewer to monitor the status. In a large domain it could be 30 minutes or
more for this process to complete.

Select Start > Run, then enter 

. When the Active Directory Wizard opens, click Next.

A dialog box indicating that this server is already a Domain Controller appears. Click Next to
demote it to a member server.

You are warned and prompted as to whether or not this is the last server in the domain. Leave
the box unchecked and click Next.

Dialogs then show the progress of the Domain Controller removal.

Click Next to finish.

Repeat this procedure for the alternate Domain Controller.

Select Start > Settings > Control Panel > Add/Remove Programs.

Select Add/Remove Windows Components > Networking Services.

Click Details.

Uncheck DNS, then click OK.

Click Next.
