You want to move a domain controller to a different site. This may be necessary if you promoted the domain controller without first adding its subnet to Active Directory. In that case, the domain controller will be added to the Default-First-Site-Name site.
Open the Active Directory Sites and Services snap-in.
In the left pane, expand Sites, expand the site where the server you want to move is contained, and expand the Servers container.
Right-click on the server you want to move and select Move.
Select the site to move the server to.

After you move a server to a new site, you might want to monitor replication to and from that server to make sure that any new connections that are needed get created and start replicating. See Recipe 12.2 for more on viewing the replication status of a server.
