COMADMIN_E_SESSION
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.
Windows describes this condition as “The server catalog version is not supported”.
Evidence to collect before repair
- Record collection name, parent key, object key, and application/partition ID.
- Preserve the exact administration method and pending property values; it anchors the failure to the real administration object.
- Evidence should include ErrorInfo entries and COM+ System Application events, captured before a repair changes state.
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 client and server Windows versions, COMAdmin interface version, remote target, and whether ICOMAdminCatalog2 features were requested.
Diagnostic sequence
- To isolate this result, recreate the catalog session and repopulate the relevant hierarchy.
- resolve objects by stable identifiers rather than display names.
- compare pending values with collection property metadata.
- The next diagnostic action is to save the smallest coherent change set and inspect ErrorInfo.
- To isolate it, 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.
