1.2 Adding Domain Controllers to Sites
If a new domain controller is added to a
forest, it will dynamically join a site with a matching subnet if the
site topology is already configured and subnets have been previously
defined. However, a preexisting domain controller will not change sites
automatically, unlike workstations and member servers. A domain
controller has to be moved manually if the topology changes. If an
existing domain controller is being moved to a new site or the site
topology or replication strategy has changed, you can follow these
steps to move a domain controller to a different site:
1. Launch Server Manager on a domain controller.
2. Expand the Tools menu and run Active Directory Sites and Services.
3. Expand the Sites folder.
4. Locate the site
that contains the desired domain controller to move. You can browse the
site servers by expanding the site and selecting the Servers container
of the site, as shown in Figure 2.
Figure 2. Browsing for site servers.
5. When you locate the desired server, take note of the source site, right-click the server name, and choose Move.
6. When a window opens listing all the sites in the forest, select the destination site, and click OK to initiate the server move.
7. When the move is
complete, verify that the domain controller has been placed in the
correct Servers container of the desired site.
Note
Although you can manually create
replication connections if the desired connections are not
automatically created by the intersite topology generator (ISTG) within
15 minutes after moving the server, the fact that the automatic
creation did not happen usually indicates a problem with site
configuration and replication.
