What does Windows error code 4057 (PEERDIST_ERROR_INVALIDATED) mean?

PEERDIST_ERROR_INVALIDATED

The supplied object has already been invalidated.

PEERDIST_ERROR_INVALIDATED is Win32 error 4057 (0xFD9) and belongs to Peer Distribution and BranchCache object lifetime after cancellation or teardown.

Troubleshooting steps

• Record the invalidating operation, object handle, generation, and later caller.
• Record the exact PeerDist function involved in object lifetime after cancellation or teardown.

What to verify

Verify whether the supplied PeerDist object has been invalidated and cannot accept further operations. Check the invalidating operation, object handle, generation, and later caller; record the exact PeerDist function involved in object lifetime after cancellation or teardown.

Handling, retry, and recovery

Release the stale object and reopen or recreate state from authoritative content information.

Difference from nearby codes

ALREADY_COMPLETED can apply to a completed operation; INVALIDATED says the object itself is no longer usable.

Practical example

A cancel path invalidates a retrieval object, but a timer later uses the old handle. Generation checks prevent the stale access.
