Generate the Replication Topology on the ISTG

Updated: October 15, 2008

Applies To: Windows Server 2008, Windows Server 2008 R2

You can use this procedure to generate the intersite replication topology on the intersite topology generator (ISTG). The Knowledge Consistency Checker (KCC) generates the Active Directory replication topology on every domain controller. The KCC runs by default every 15 minutes.

You can force the KCC to run on any domain controller. The topology that is generated depends on the domain controller on which you run the command. You can force the KCC to run as follows:

  • To generate the intersite replication topology, run the KCC on the domain controller in the site that holds the ISTG role.

  • To generate the intrasite replication topology, run the KCC on any domain controller in the site that does not hold the ISTG role.

noteNote
To generate the replication topology on the ISTG, you must first complete the procedure: Determine the ISTG Role Owner for a Site.

Membership in Enterprise Admins, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

  1. Determine the server that holds the ISTG role for the site.

  2. Open Active Directory Sites and Services: On the Start menu, point to Administrative Tools, and then click Active Directory Sites and Services.

  3. In the console tree, expand Sites, and then expand the site that contains the ISTG on which you want to run the KCC.

  4. Expand Servers, and then click the Server object for the ISTG.

  5. In the details pane, right-click NTDS Settings, click All Tasks, and then click Check Replication Topology.

  6. In the Check Replication Topology message box, click OK.
