Too few global catalog servers in site

Indicates if the number of global catalog servers in a given site is less than or equal to the configured threshold.

Requirements

•

Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019

•

Required permissions: Domain user privilege is required.

Description

Each site in an Active Directory® enterprise should have at least one domain controller configured as a global catalog. The workstation login process always attempts to contact a global catalog server, and if none are running at the site where the workstation resides, the workstation will connect to a global catalog server outside of the site, which can cause excess WAN traffic and unnecessary delays in the login process.

Resolution

•

Configure a domain controller as a global catalog server.

Customizing the topology layout

Viewing Active Directory forest topology

For a selected forest, you can view and customize a topology diagram, and quickly see a list of domain controllers with their roles.

To view Active Directory topology

Open the Web Console. See Opening the Web Console.

Select Monitor | Active Directory Topology.

Type a forest name, or click in the box to select from a list of previously discovered forests.

Every three hours, the Active Administrator® Foundation Service (AFS) server updates the topology data in the cache with the latest data from Active Directory® Service. If you want to update the forest topology data when you run the topology and update the domain controller list, select Update topology. Otherwise, if the check box is not selected, the forest topology data is loaded from the cache.


	NOTE: Once you click to load the forest topology data and update the domain controller list, the check box is hidden from the display. To restore the check box, clear the forest name box.

Click

to load the forest topology data.


	NOTE: If you typed a forest name that is not in the list of previously discovered forests or if the Update topology check box is selected, a pop-up message displays every 15 seconds while data is being collected by the computer running Active Administrator®. If the forest is large, there may be a delay loading the domain controller list.

Select the domain controllers.

To filter the list, start typing in the Search domain controllers box. The list filters as you type. To clear the filter, press Esc.


	NOTE: It is recommended that you limit the number of domain controllers in the diagram to 80 or less.

Click Run.

The Topology tab opens to display an interactive forest topology diagram. The intra-site replication links are shown in blue and the inter-site replication links are shown in gray. You can click and drag the sites and domain controllers to rearrange the diagram. See Customizing the topology layout.

Use the tool bars to manipulate the topology diagram. There are two tool bars for the Topology Viewer. One is located at the top of the page and the second is located below the diagram design area
