What does HRESULT 0xC00E0067 (MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW) mean?

MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW

Operational meaning

Applications should keep MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW attached to the exact MSMQ call that produced it; translating it immediately to “queue error” discards the diagnostic boundary. In this case the decisive subject is dependent-client capacity limit reached. This reflects the historical licensing/topology ceiling of the serving MSMQ system.

For MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, establish the originating binary, operating-system build, MSMQ generation, and migration phase. When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, if those cannot be proved, treat the code as historical context rather than a current configuration prescription.

When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, A legacy code found in an event archive is evidence about the deployment generation. In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, copying old DLLs or registry settings into a current Windows installation can make the system less recoverable.

Where to draw the boundary

When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, compatibility names can outlive the component that once emitted them. In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, remediation must match the historical architecture, not only the symbolic text. For MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, the code-specific boundary is dependent-client capacity limit reached.

Evidence to preserve

• Whether a current api returned the value or an old log merely contains it; associate it explicitly with MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW.
• When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, windows and msmq version where the code was captured; capture the value before cleanup or retry changes it.
• In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, installation or migration component name and original event text; compare it with a known-good call using the same account and queue type.
• For this MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW result, record the queue path or format name, local/remote placement, transactional flag, caller SID, process build, and UTC correlation ID when they apply.

For MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, log certificate thumbprints, provider names, SIDs, GUIDs, lengths, and hashes where useful, but do not log private keys, symmetric keys, credentials, or confidential message bodies.

Diagnostic sequence

1. Record the unsigned HRESULT, MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, and the native API or COM method before a framework replaces it with a generic exception.
2. When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, verify the postcondition after the failed call: queue existence, message presence, directory object state, transaction outcome, or generated output may differ by result.
3. In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, capture installation or migration component name and original event text.
4. For this MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW result, capture whether a current API returned the value or an old log merely contains it.
5. Reproduce with the smallest queue/message/property set that still returns MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW; change one precondition at a time.
6. When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, apply the code-specific recovery rule: Inventory clients and product versions instead of retrying connections.

Handling and recovery

Inventory clients and product versions instead of retrying connections.

When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, do not hide this HRESULT behind an unlimited framework retry. In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, require a verified precondition change and preserve the original correlation identifier across the next attempt.

Nearby failure boundaries

In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, do not copy retired DLLs or recreate obsolete registry topology until the originating MSMQ generation and component are proved. The specific focus for MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW remains dependent-client capacity limit reached.

• In the MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW path, restarting MSMQ before collecting evidence can invalidate handles and erase the first useful event; it is a containment action, not a root-cause diagnosis.
• For this MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW result, granting broad queue or certificate permissions may mask the symptom while creating a security defect. For MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, test the exact identity and access needed by the operation.

Worked example

A migration assistant encounters MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW. For MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, it identifies the originating MSMQ generation and uses migration documentation instead of modifying a current installation blindly. When diagnosing MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, the acceptance test then changes only the decisive precondition and confirms both the HRESULT and the actual queue/message state.

A regression test should force MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW, assert the raw value and relevant outputs, then correct only the documented precondition and verify the intended success or neighboring HRESULT.

Historical dependent-client capacity

MQ_ERROR_DEPEND_WKS_LICENSE_OVERFLOW belongs to the old dependent-client deployment model, in which a supporting Message Queuing server served a bounded population of clients. The useful evidence is the count and identity of dependent clients, the product edition and license terms active at the time, and whether stale registrations remained after computers were retired or renamed. Modern retry logic cannot create capacity in that topology.

• Reconstruct the serving relationship from original administration data rather than from current DNS names alone.
• Check whether the application can be moved to an independent/full MSMQ installation or a supported server role.
• Preserve the historical configuration before migration because the same symbolic code may never be emitted by a current Windows release.
