CO_E_NO_SECCTX_IN_ACTIVATE
COM+ activation callback has no security context
CO_E_NO_SECCTX_IN_ACTIVATE is HRESULT 2147500075 (0x8000402B) from winerror.h. The documented description is “Unable to complete the call since there is no COM+ security context inside IObjectControl.Activate.” The value must be interpreted at IObjectControl::Activate or related COM+ object activation code expecting caller security information.
The activation callback is running without the COM+ security context required by the component. For reliable triage of this result, store the native HRESULT and symbolic identity before generic error handling rewrites either one.
Where the result appears
- This result may surface in IObjectControl::Activate or related COM+ object activation code expecting caller security information.
Typical causes and interpretation
Common cause categories are: security is disabled; the object is activated outside COM+; context propagation failed; the component assumes a caller token that is not guaranteed. Investigate this result through falsifiable cause hypotheses and keep the first lower-level failure that explains the observed HRESULT.
Key distinction: the activation callback is running without the COM+ security context required by the component.
Correct handling and recovery
The appropriate recovery is to make security requirements explicit, query context only where COM+ guarantees it, and reject or degrade safely without manufacturing an identity. Do not loop on it; retry only under a documented transient condition with bounded delay and post-operation reconciliation.
After observing it, separate local resource cleanup from server-side reconciliation and perform each only for the failing activity ID.
Practical scenario
A pooled component reads caller roles during Activate, but the application has component-level security disabled; configuration is corrected and checks move to the call boundary.
Difference from related HRESULTs
CO_E_FAILEDTOGETSECCTX means retrieval of an expected context failed; this code says no such context exists inside Activate.
Preserve the neighboring-result distinction in metrics and incident reports to avoid applying the wrong remediation.
