FSMO Roles drilldown

The Flexible Single-Master Operation (FSMO) Roles drilldown indicates which domain controller owns each FSMO role. It also indicates which domain controller is the Global Catalog (GC) server.

NOTE: By default, the FSMO Roles drilldown collects only the FSMO roles for the domain where the domain controller is located. Select Collect FSMO role holders from other domains to collect all FSMO roles in the forest. If selected, this check box is applied to all current connections as well as new future connections.

The FSMO Roles drilldown displays the following information.


The five main roles a server can fulfill. These include Domain Naming Master, Schema Master, Infrastructure Master, PDC Emulator, and RID Server.

Global Catalog and Intersite Topology Generator are not FSMO roles; they are listed here as extra information.

Domain Controller

The network name of the computer that fulfills the associated FSMO role.


The name of the domain to which the computer belongs.


The site to which the computer belongs.

IP Address

The IP address of the computer.


Alerts Appendix

This appendix provides details on the alerts within the Active Directory Health Analyzer. Along with a detailed description of the event that triggers the alert, a resolution is provided.
