COMADMIN_E_AMBIGUOUS_APPLICATION_NAME

COMADMIN_E_AMBIGUOUS_APPLICATION_NAME is the failure HRESULT 0x8011045C (signed decimal -2146368420, unsigned decimal 2148598876). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x045C.

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

An application name resolves to more than one application and cannot be converted to a unique AppID. A COMAdmin method accepts name or ID and name-based resolution returns multiple candidates.

AllStat records this condition as “The application name is not unique and cannot be resolved to an application id”.

Where COMADMIN_E_AMBIGUOUS_APPLICATION_NAME 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 COMADMIN_E_AMBIGUOUS_APPLICATION_NAME, enumerate applications with the name across relevant partitions and record their AppIDs.

Evidence to collect before repair

  • Collect all matching application names, AppIDs, and partition IDs when diagnosing COMADMIN_E_AMBIGUOUS_APPLICATION_NAME; without it the symbolic HRESULT is underdetermined.
  • The COMADMIN_E_AMBIGUOUS_APPLICATION_NAME investigation needs the current catalog partition context so the exact failing boundary remains reconstructable.
  • For COMADMIN_E_AMBIGUOUS_APPLICATION_NAME, preserve the name or ID passed to the failing method; it anchors the failure to the real administration object.
  • Evidence for COMADMIN_E_AMBIGUOUS_APPLICATION_NAME should include deployment history for each matching application, captured before a repair changes state.

Diagnostic sequence for COMADMIN_E_AMBIGUOUS_APPLICATION_NAME

  • The next COMADMIN_E_AMBIGUOUS_APPLICATION_NAME diagnostic action is to enumerate matching applications across relevant partitions.
  • To isolate COMADMIN_E_AMBIGUOUS_APPLICATION_NAME, select the intended application by AppID.
  • For COMADMIN_E_AMBIGUOUS_APPLICATION_NAME, update automation to persist IDs with partition context.
  • At the COMADMIN_E_AMBIGUOUS_APPLICATION_NAME boundary, rename duplicates only when operationally safe.
  • The next COMADMIN_E_AMBIGUOUS_APPLICATION_NAME diagnostic action is to repeat the operation and log the resolved AppID.

Practical administration scenario

A script addresses Billing by display name after separate partitions introduce multiple Billing applications.

Retry and recovery

Call the API with the explicit AppID or rename applications to preserve operational uniqueness.

Difference from nearby COMADMIN results

COMADMIN_E_APPLICATIONEXISTS blocks duplicate creation; this value arises later when an ambiguous name is used for lookup.
