Active Directory Overview (Topology Report)

This topic discusses the "Active Directory Overview (Topology Report)" page.

Overview

The Topology Report displays a view of all of the AD forests, domains, and domain controllers known to the Splunk App for Microsoft Exchange at the present time. You can return to this dashboard at any time by selecting Active Directory > Active Directory Overview'.

The Topology Report page splits into two halves, upper and lower. The upper half of the page is a selection panel which allows you to choose the forests, sites, domains, and domain controllers that the Splunk App for Microsoft Exchange knows about.

The lower half of the page displays additional information based on what you select on the upper half. It displays detailed information on the domain controllers in the selected forest and domain, and includes the following statistics:

• The host name of the domain controller (DC).
• The AD site that the DC belongs to.
• The operating system and version of Windows the server runs.
• The AD Flexible Single Master Operation (FSMO) role(s) the server holds.
• Information on the Directory Service Agent (DSA) options available for the DC.
• Information on the status of the AD services that the machine runs.
• Information on whether or not the server has registered itself in DNS.
• Information on whether or not the machine's SYSVOL share is available on the network.

In this dashboard, icons in the "Masters Roles" column indicate the operations master roles for each server.

Icon	Role	Description
	Schema Master	The Schema Master controls all updates to the Active Directory's schema, then replicates it to all other domain controllers in the forest. There can be only one Schema Master in an entire forest.
	Domain Naming Master	The Domain Naming Master controls the naming of all domains within the forest. It is the only domain controller that can add or remove domains from Active Directory. As such, only one Domain Naming Master can be present in a forest.
	Relative ID Master	The Relative ID Master domain controller maintains the relative ID (RID) resource pool and is responsible for allocating RIDs to other domain controllers within a domain when they are requested during the creation of security principle objects like users and groups. There can only be one RID Master in a domain.
	PDC Emulator Master	This domain controller emulates the Primary Domain Controller (PDC) role for a domain and handles time synchronization across the domain. It also handles various PDC duties (such as password changes, account lockouts and GPO manipulation) for domains which have both Windows Server 2000 and Server 2003 domain controllers present. Only one PDC emulator can be present in a domain.
	Infrastructure Master	The Infrastructure Master handles updates to the security identifier (SID) and distinguished name (DN) of an object that is cross-referenced by another object in another domain. There can only be one Infrastructure Master in a domain.

The DSA options are listed as icons under the "DSA Options" column:

• A globe indicates that the server is a Global Catalog (GC).
• A padlock indicates that the server is a Read-only Domain Controller (RODC).

How to use this page
