COMADMIN_E_COMP_MOVE_LOCKED
Moving a component between COM+ applications: exact meaning of COMADMIN_E_COMP_MOVE_LOCKED
COM+ refuses a component move because the source or destination application is protected or locked. MoveComponent evaluates both application endpoints before changing ownership of the component catalog entry.
Windows describes this condition as “The component move was disallowed, because the source or destination application is either a system application or currently locked against changes”.
Where the result occurs
A component move changes catalog ownership and service configuration; both source and destination applications must remain valid, mutable, and explicitly identified throughout the operation. In the specific case of this result, record source and destination AppIDs, system-application status, active deployment locks, and concurrent administration activity.
Evidence to collect before repair
- Evidence should include component CLSID and current application ID, captured before a repair changes state.
- Collect source and destination AppIDs and application types when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record catalog lock/concurrent deployment timeline.
- Preserve fresh Applications and Components collection snapshots; it anchors the failure to the real administration object.
Diagnostic sequence
- repopulate both endpoints immediately before the move.
- The next diagnostic action is to reject system, proxy, or missing applications.
- To isolate this result, stop conflicting deployment rather than forcing catalog edits.
- Perform the move through COMAdmin.
- verify interfaces, roles, and component properties in the destination.
Difference from nearby COMADMIN results
COMADMIN_E_COMP_MOVE_BAD_DEST means the destination disappeared; this value means an existing endpoint is not eligible for modification.
Retry and recovery
Choose ordinary unlocked applications and retry only after the catalog lock or protected target condition is removed.
Practical administration scenario
An administrator tries to move a component into the System Application and COM+ blocks the operation.
