COMADMIN_E_CAT_SERVERFAULT

COMADMIN_E_CAT_SERVERFAULT is the failure HRESULT 0x80110486 (signed decimal -2146368378, unsigned decimal 2148598918). Its severity bit is 1, facility is 17 (FACILITY_ITF), and the facility-specific code field is 0x0486.

Unhandled fault inside the COM+ Catalog Server: exact meaning of COMADMIN_E_CAT_SERVERFAULT

The catalog server threw an exception while carrying out the administration operation. The public HRESULT does not specify the exception type or prove that the persistent catalog is damaged.

AllStat records the Windows SDK description as “The COM+ Catalog Server threw an exception during execution”.

Typical cause branches

  • an internal catalog-server defect or unexpected state reached by the request.
  • damaged or inconsistent catalog data caused an unhandled path during execution.
  • a third-party registration callback or component inspection path faulted inside administration work.
  • system resource, storage, or servicing damage destabilized the catalog server process.

Where COMADMIN_E_CAT_SERVERFAULT occurs

This value is broader than an object-validation or file error: control reached the COM+ Catalog Server and failed during execution. The first COM+ event, Windows Error Reporting entry, or subordinate exception is therefore more informative than repeated outer HRESULTs.

Evidence to collect before changing the catalog

  • the first Application and System event entries for COM+, COMSysApp, Dllhost, or Windows Error Reporting.
  • operation name, target machine, collection hierarchy, object keys, and pending values.
  • faulting module, exception code, process ID, dump identifier, and OS build.
  • catalog backup status, recent servicing, disk errors, and whether the fault reproduces on one object or all operations.

Diagnostic sequence for COMADMIN_E_CAT_SERVERFAULT

  • stop automatic retries so the earliest crash/fault evidence is not overwritten.
  • reproduce with the smallest read-only or single-object operation that reaches the same path.
  • separate a catalog-wide service fault from one component registration callback.
  • repair OS/component servicing or restore a known-good catalog only through supported procedures.
  • escalate with dump, event sequence, and exact object data when the fault survives system repair.

Difference from nearby COMADMIN results

COMADMIN_E_REGDB_SYSTEMERR reports an underlying system error in the registration database; COMADMIN_E_OBJECTERRORS aggregates object-level failures. This code identifies an exception escaping catalog-server execution.

Retry and recovery

Retry only after the catalog server has restarted and the suspected object, callback, resource condition, or servicing problem has changed. A rapid retry loop can repeatedly crash the service and obscure the first fault.

What this HRESULT does not establish

The symbolic value alone does not establish catalog corruption, malware, or a specific failing module. Those conclusions require event or dump evidence from the same execution.

Practical administration scenario

Saving one imported component consistently terminates catalog processing, and Windows Error Reporting names a registration helper module; other application collections populate normally.

Developer and operations guidance

Capture correlation ID, COMAdmin method, object keys, server PID, exception code, faulting module/version, OS build, first event record IDs, and retry count. Preserve a dump reference rather than embedding sensitive dump data in normal logs.
