Technical Meaning

The error code ERROR_DS_DRA_NAME_COLLISION (8458, 0x210A) indicates that a replication operation failed because of a name collision. This typically occurs when two or more objects in the directory service have the same name within the context of a replication process.

Error Details

This error is specific to directory services and replication operations. It suggests that during the synchronization or update process, an attempt was made to replicate an object with a name that already exists in the target location, leading to a conflict.

Usage Context

The error ERROR_DS_DRA_NAME_COLLISION can be encountered when using Active Directory Domain Services (AD DS) for replication purposes. It is part of the directory replication agent (DRA) operations and indicates an issue with object naming during the synchronization process.

Developer Interpretation

When this error occurs, it means that a name collision has been detected during a replication operation. This could be due to various reasons such as incorrect naming conventions or issues in the source data being replicated. Developers should ensure that names are unique within their directory service to avoid such conflicts.
