Determine the ISTG Role Owner for a Site
The Intersite Topology Generator (ISTG) is the domain controller in each site that is responsible for generating
the intersite topology. If you want to regenerate the intersite topology, you must determine the identity of the
ISTG role owner in a site. You can use this procedure to view the NTDS Site Settings object propertiesand
determine the ISTG role owner for the site.
To determine the ISTG role owner for a site
1. OpenActive Directory Sites and Services.
2. In the console tree, click the site object whose ISTG role owner you want to determine.
3. In the details pane, right-click the NTDS Site Settings object, and thenclick Properties. The current
role owner appears in the Server box under Inter-Site Topology Generator.
