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

The remote or local server catalog version is not supported by the administration session. COMAdmin establishes a catalog session and detects a version/protocol mismatch before reliable collection work.

AllStat records this condition as “The server catalog version is not supported”.

Evidence to collect before repair

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

Where COMADMIN_E_SESSION 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_SESSION, record client and server Windows versions, COMAdmin interface version, remote target, and whether ICOMAdminCatalog2 features were requested.

Diagnostic sequence for COMADMIN_E_SESSION

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

Retry and recovery

Use administration tooling supported by the target version or perform management locally with compatible components.

Practical administration scenario

A management host with newer assumptions connects to an older COM+ server whose catalog session version it cannot support.

Difference from nearby COMADMIN results

COMADMIN_E_MIG_VERSIONNOTSUPPORTED concerns catalog migration, while this code concerns the live administration session.
