PEERDIST_ERROR_TRUST_FAILURE
Communication with one or more computers will be temporarily blocked due to recent errors.
PEERDIST_ERROR_TRUST_FAILURE is Win32 error 4066 (0xFE2) and belongs to Peer Distribution and BranchCache peer trust and temporary blocking.
Troubleshooting steps
- Record affected peer identities, certificate or hash validation results, timestamps, and security events.
- Record the exact PeerDist function involved in peer trust and temporary blocking.
What to verify
Verify whether recent authentication, validation, or protocol failures caused communication with one or more computers to be temporarily blocked. Check affected peer identities, certificate or hash validation results, timestamps, and security events; record the exact PeerDist function involved in peer trust and temporary blocking.
Handling, retry, and recovery
Do not bypass the block; correct time, identity, content integrity, or policy problems and allow the trust mechanism to recover.
Difference from nearby codes
MISSING_DATA is about availability, whereas TRUST_FAILURE deliberately suppresses communication after security-relevant errors.
Practical example
A misconfigured branch host repeatedly presents invalid data and becomes temporarily blocked.
Developer and administrator guidance
Keep the peer identity, blocked-until time, content hash result, authentication evidence, and security event. Correct the peer or trust input and let the protection recover; do not clear the block by disabling BranchCache validation.
