Information only.

 
Table 5. Forest details
Field
Description

Forest

Name of the forest.

Domains

Number of domains.

Domain controllers

Number of domain controllers.

Sites

Number of sites.

Empty sites

Number of empty sites.

GC servers

Number of global catalog (GC) servers.

RODC servers

Number of read-only domain controllers (RODCs).

Application partitions

Number of application partitions.

Bridgehead servers

Number of bridgehead servers.

Functional level

Functional level of the site.

Domain naming master

Name of the domain controller with the domain naming master role.

Schema master

Name of the domain controller with the schema master role.

Operations master consistent

Indicates if all the domain controllers report the same operation masters.

Schema master consistent

Indicates if all the domain controllers report the same schema masters.

Functional level consistent

Indicates if all the domain controllers report the same functional level.

Naming operations master inconsistent

Indicates that the naming operations master is not consistent among all domain controllers in the forest.

Requirements
•
Supported on: Windows Server 2016, Windows Server 2019, and Windows Server 2022
•
Required permissions: Domain user privilege in all domains in the forest.
Description

The domain naming operations master is contained in the fSMORoleOwner property of the CN=Partitions,CN=Configuration,DC=<root domain> container. Because the partitions container is part of the configuration naming context, every domain controller in the forest has a copy of the domain naming operations master. The domain naming operations master determines what domain controller in the forest can initiate a domain renaming operation. If the domain naming operations master is inconsistent, it is possible to issue a domain renaming operation simultaneously at two different domain controllers, with potentially disastrous consequences.

The domain naming operations master can become inconsistent because an administrator used NTDSUTIL.EXE to move the operations master when there was incomplete connectivity to all domain controllers. It can also occur because of replication errors.

Resolution
•
Make sure that no one attempts to rename a domain.
•
Wait to see if the error clears. If an administrator has moved an operations master to another domain controller, replication to all domain controllers in the forest can take a long time.
•
If the situation does not clear, contact your Microsoft® Windows® support representative.

Naming operations master is not a global catalog server

Indicates that a server possessing the domain naming operations master does not host a global catalog (GC).

Requirements
•
Supported on: Windows Server 2016, Windows Server 2019, and Windows Server 2022
•
Required permissions: Domain user privilege in the domain where the schema and naming masters reside.
Description

The domain naming operations master must be a global catalog server because the domain naming operations master is responsible for creating objects that represent new domains. In order to do this, the domain naming operations master must be able to make sure that no other object — whether it is a domain object or not — has the same name as the new domain object. The domain naming operations master always runs a global catalog, which contains a partial replica of every object, to allow the domain naming operations master to quickly check for a duplicate object name prior to creating a new domain object.

Resolution
•
Enable a global catalog on the domain naming operations master.
