What does HRESULT 0x80110602 (COMQC_E_QUEUING_SERVICE_NOT_AVAILABLE) mean?

COMQC_E_QUEUING_SERVICE_NOT_AVAILABLE

COMQC_E_QUEUING_SERVICE_NOT_AVAILABLE — 0x80110602

This code places the first failure in MSMQ dependency for COM+ queued components. Operationally, COM+ cannot perform queued activation because Microsoft Message Queuing is absent, disabled, unreachable, or not available in the required configuration.

The contract behind the HRESULT

Queued Components cross several independent layers: call recording, MSMQ transport, message authentication, listener playback, and execution of the business method. Message ID, queue format name, original sender, any mover or requeuer, and the COM+ application version are the keys that join those layers without treating every queue symptom as the same fault.

A stopped COM+ listener differs from a missing/unavailable Message Queuing substrate.

Diagnostic worksheet

• MSMQ feature installation, service state, workgroup/domain mode, and queue manager identity
• COM+ application queue path/format name and transactional requirement
• Service dependencies and event logs from MSMQ and COM+
• Local versus remote destination and firewall/name-resolution state

Reproduce the condition safely

1. Create and read a simple private queue outside COM+.
2. Use a local direct format name to separate directory lookup from queue service health.
3. Restart only MSMQ and the queued-component listener after preserving pending messages.

Closing the incident

A defensible correction is specific to the evidence: Install and configure the supported MSMQ feature, restore queue-manager health, and validate the exact destination format/transaction mode.

Close the incident only when messages can be enqueued, survive sender exit, and are consumed after listener restart without loss or duplicate business effects.
