ERROR_DS_ALIASED_OBJ_MISSING - 8334 (0x208E)
The aliased object is missing.
Updated: Feb 21, 2026
Technical Meaning
This error code indicates that an object, which is expected to be aliased or linked to another object, is missing. In the context of Windows Active Directory Services (ADS), this can occur when a reference to an object cannot be resolved because the target object does not exist.
Error Details
The term 'aliased' in this context refers to objects that are referenced by other objects or services within the directory. When such a reference is made, it typically points to another object's unique identifier (GUID) or distinguished name. If the aliased object cannot be found, this error is generated.
Usage Context
This error can arise in various scenarios where an alias or reference is expected to resolve to a specific object within the directory structure. Common contexts include:
- Directory services operations that rely on aliases for object references.
- LDAP queries and searches that depend on aliased objects.
- Operations involving cross-referencing between different parts of the directory.
Developer Interpretation
When encountering this error, developers should consider the following aspects:
- Verify that all referenced objects exist in the directory.
- Ensure that any aliases used are correctly configured and point to valid targets.
- Check for any recent deletions or modifications that might have affected the referenced object.
- Validate the integrity of the directory structure and ensure no corruption has occurred.
