Removing a Site

Updated: March 2, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

If domain controllers are no longer needed in a network location, you can remove them from the site and then delete the Site object. Before deleting the site, you must remove domain controllers from the site either by removing it entirely or by moving it to a new location.

  • To remove the domain controller, remove Active Directory from the server and then delete the Server object from the site in Active Directory.

  • To retain the domain controller in a different location, move the domain controller to a different site and then move the Server object to the respective site in Active Directory.

Domain controllers can host other applications that depend on site topology and publish objects as Child objects of the respective Server object. For example, when MOM or Message Queuing is running on a domain controller, these applications create Child objects beneath the Server object. In addition, a server running Message Queuing that is not a domain controller and is configured to be a routing server running Message Queuing creates a Server object in the Sites container. Removing the application from the server automatically removes the Child object below the respective Server object. However, the Server object is not removed automatically.

When all applications have been removed from the server (no Child objects appear beneath the Server object), you can remove the Server object. After the application is removed from the server, a replication cycle might be required before Child objects are no longer visible below the Server object.

After you delete or move the Server objects but before you delete the Site object, reconcile the following objects:

IP addresses:

  • If the addresses are being reassigned to a different site, associate the Subnet object or objects with that site. Any clients using the addresses for the decommissioned site will thereafter be assigned automatically to the other site.

  • If the IP addresses will no longer be used on the network, delete the corresponding Subnet object or objects.

Site Link objects:

  • If the site you are removing is added to a site link containing only two sites, delete the Site Link object.

  • If the site you are removing is added to a site link that contains more than two sites, do not delete this Site Link object.

Before removing a site, you need to consider the implications. If the site you are removing is added to more than one site link, it might be an interim site between other sites that are added to this site link. Deleting the site might disconnect the outer sites from each other. In this case, the site links must be reconciled according to the instructions of the design team.

Task Requirements

The following tool is required to perform the procedures for this task:

  • Active Directory Sites and Services

To complete this task, perform the following procedures:

  1. Determine whether a Server object has child objects

  2. Delete a Server object from a site

  3. Delete the Site Link object

  4. Associate the subnet or subnets with the appropriate site

  5. Delete the Site object

  6. To avoid replication errors on bridgehead servers in other sites that received replication from the site that has been removed, generate the intersite topology in those sites by performing the following two procedures:
