What does Windows error code 4061 (PEERDIST_ERROR_OUT_OF_BOUNDS) mean?

PEERDIST_ERROR_OUT_OF_BOUNDS

An operation accessed data beyond the bounds of valid data.

PEERDIST_ERROR_OUT_OF_BOUNDS is Win32 error 4061 (0xFDD) and belongs to Peer Distribution and BranchCache content range validation.

Troubleshooting steps

• Record total content length, overlapped offset, requested length, and arithmetic before the API call.
• Record the exact PeerDist function involved in content range validation.

What to verify

Verify whether an offset or length addresses bytes outside the valid content extent. Check total content length, overlapped offset, requested length, and arithmetic before the API call; record the exact PeerDist function involved in content range validation.

Handling, retry, and recovery

Validate range addition for overflow and clamp only when the protocol explicitly permits partial data.

Difference from nearby codes

MISSING_DATA concerns a valid range that cannot be found; OUT_OF_BOUNDS says the range itself is invalid.

Practical example

A 32-bit length calculation wraps before PeerDistClientAddData and produces an offset beyond end-of-content; checked arithmetic fixes it.
