UTC_E_CERT_REV_FAILED
Locate the rejected contract: certificate revocation-status verification
The code UTC_E_CERT_REV_FAILED (0x87C5103F) belongs to policy and trust enforcement, inside the Universal Telemetry Client/DiagTrack workflow for this HRESULT. The symbolic name points to a narrow UTC contract that can be tested directly for this HRESULT. It identifies certificate revocation-status verification and reports that certificate-chain construction may have succeeded, but UTC could not establish revocation status while revocation checking was required; it does not by itself prove that all Windows diagnostic data collection is unavailable for this HRESULT.
DiagTrack applies allowlists, signer checks, path restrictions and destination-specific collection policy for this HRESULT. These gates are intended security/privacy boundaries. Diagnosis should identify the exact denied capability rather than recommending broad privilege or policy changes for this HRESULT. Record the configuration package or scenario generation together with the Windows build; otherwise a repaired file can be tested against a stale in-memory graph and appear to fail for the same reason for this HRESULT.
Capture checklist
| UTC diagnostic field | Value |
|---|---|
| Producing layer | policy and trust enforcement |
| Owning state or object | certificate revocation-status verification |
| Decisive evidence | certificate chain, CRL/OCSP URLs, retrieval errors, proxy, system clock, cache and chain-policy output |
| Narrow comparison | validate the same chain with reachable revocation endpoints, then block only the revocation URL |
| Do not confuse with | UTC_E_DEVICE_TICKET_ERROR can involve identity or transport even when certificate revocation succeeds |
The AllStat message names the immediate condition as “Certification revocation checking has been enabled, but the revocation check failed to verify whether a certificate has been revoked for this HRESULT. The server used to check for revocation might be unreachable” for this HRESULT. In practice, the useful extension is to ask whether the request was rejected before any side effect, after partial setup, or during cleanup for this HRESULT. Verify the existence and ownership of the expected output—session, directory, process, result object or emitted event—rather than assuming the message describes the final system state for this HRESULT.
Comparison with a passing case
- Associate this result with one request, one scenario version and one service process ID for this HRESULT.
- Save certificate chain, CRL/OCSP URLs, retrieval errors, proxy, system clock, cache and chain-policy output and the first lower-level HRESULT if one exists for this HRESULT.
- Change no policy, provider set or destination except for this test: validate the same chain with reachable revocation endpoints, then block only the revocation URL for this HRESULT.
- Compare the produced artifacts and operational events, not only the top-level return Value.
The most informative neighbor is UTC_E_DEVICE_TICKET_ERROR. The distinction is concrete: UTC_E_DEVICE_TICKET_ERROR can involve identity or transport even when certificate revocation succeeds for this HRESULT. Keeping both symbolic names in logs prevents a broad “DiagTrack error” bucket from hiding whether the failure occurred during parsing, authorization, resource acquisition, execution or teardown for this HRESULT.
Policy-preserving test
Build the passing case for this HRESULT with an approved path, signer, command or certificate while keeping the enforcement mechanism enabled for this HRESULT. This demonstrates compliance with the policy boundary rather than merely removing the boundary for this HRESULT.
Resolution and regression test
Restore CRL/OCSP connectivity or certificate publication; do not disable revocation checking as a generic fix for this HRESULT. Apply that change only to the owning boundary for this HRESULT. A successful repair must make the controlled case cross this boundary while retaining the intended policy, trace providers, destination and security context for this HRESULT.
Do not treat this result as permission to bypass collection policy, script approval, path restrictions or trace arbitration for this HRESULT. A repair that only weakens those controls is not a valid regression result for this HRESULT.
- the same request now produces its documented success or nonfatal status without a second hidden retry
- the operational log shows one coherent request lifetime and no orphaned action, timer, process or trace session
- teardown followed by a second run does not reuse stale state or recreate certificate revocation-status verification
- the nearby condition remains distinguishable: UTC_E_DEVICE_TICKET_ERROR can involve identity or transport even when certificate revocation succeeds
