COM+ catalog object and collection state: exact meaning of COMADMIN_E_OBJECTEXISTS

An object with the requested identity already exists in the target collection. Add or rename work reaches uniqueness validation for a catalog collection.

AllStat records this condition as “The object you are attempting to add or rename already exists”.

Where the result occurs

The authoritative state is the logical COM+ catalog exposed through COMAdmin collections, not a single registry key or an old in-memory object. In the specific case of this result, record collection name, proposed key/name, existing object key, and normalization rules.

Evidence to collect before repair

  • Collect collection name, parent key, object key, and application/partition ID when diagnosing this result; without it the symbolic HRESULT is underdetermined.
  • The result investigation needs the exact administration method and pending property values so the exact failing boundary remains reconstructable.
  • preserve ErrorInfo entries and COM+ System Application events; it anchors the failure to the real administration object.
  • Evidence for it should include a fresh Populate result taken before any repair, captured before a repair changes state.

Diagnostic sequence

  • The next this result diagnostic action is to recreate the catalog session and repopulate the relevant hierarchy.
  • To isolate it, resolve objects by stable identifiers rather than display names.
  • compare pending values with collection property metadata.
  • At the boundary, save the smallest coherent change set and inspect ErrorInfo.
  • The next it diagnostic action is to verify the committed object by repopulating after SaveChanges.

Practical administration scenario

A deployment renames a role to a name already used by another role in the same application.

Retry and recovery

Update the intended existing object or choose a deliberate unique identity; avoid suffix-based duplication.

Difference from nearby COMADMIN results

COMADMIN_E_APPLICATIONEXISTS and COMADMIN_E_COMPONENTEXISTS are narrower application/component variants.
