Domain details

Information only.

 
Table 6. Domain details
Field
Description

Domain

Name of the selected domain.

Domain controllers

Number of domain controllers.

GC servers

Number of global catalog (GC) servers

RODC servers

Number of read-only domain controllers (RODCs)

Functional level

Functional level of the forest, domain, or site

PDC owner

Owner of the primary domain controller (PDC) Flexible Single Master Operation (FSMO) role

RID master

Owner of the relative identifier (RID) FSMO role

Infrastructure master

Owner of the infrastructure FSMO role

Operations master consistent

Indicates if all the domain controllers report the same operation masters

Functional level consistent

Indicates if all the domain controllers report the same functional level

FSMO placement

Indicates that Active Directory® Flexible Single-Master (FSMO) roles are not configured according to Microsoft® recommendations.

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

The Active Directory Installation Wizard performs the initial placement of roles on domain controllers and is often correct for directories that have just a few domain controllers. A directory that has many domain controllers may require manual intervention to optimize placement.

Resolution
•
Place the schema master on the PDC of the forest root domain.
•
Place the domain naming master on the forest root PDC.
•
Place the RID master on the domain PDC in the same domain.
•
Legacy guidance suggests placing the infrastructure master on a non-global catalog server.

GC replication latency

Indicates that the replication latency of the server that hosts a replica of the global catalog equals or exceeds the configured threshold.

Requirement
•
Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
•
Required permissions: Domain user privileges with rights to list contents, create objects, read and write properties under the AATemp organizational unit in the domain root.
Resolution
•
Check connectivity between both the domain controller and the replication partner in question.
•
Check to see that the link is reasonably clear, especially during replication.
•
Check the replication schedule for the connection.
•
Make sure that each partner has adequate CPU and memory resources to ensure timely servicing of replication requests.
•
Make sure that the link between partners is adequate for the amount of traffic carried during replication.

Infrastructure master host GC

Indicates that the infrastructure operations master hosts a global catalog server.

Requirement
•
Supported on: Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, and Windows Server 2019
•
Required permissions: Domain user privilege is required.
Description

The infrastructure operations master updates references from objects in other domains by comparing local data to data from a global catalog, which is always up to date. If discrepancies are found, the infrastructure operations master updates the local object data from the global catalog, and then replicates the updated object data to all other domain controllers in the domain. If a global catalog exists on the same domain controller as the infrastructure operations master, the infrastructure operations master will never find data that is out of date.

Resolution

Remove the global catalog from the infrastructure operations master domain controller.
