ERROR_GRAPHICS_CHAINLINKS_NOT_ENUMERATED
What Windows rejected: graphics chainlinks not enumerated
ERROR_GRAPHICS_CHAINLINKS_NOT_ENUMERATED, value 0xC0262432, is produced by linked when one or more linked adapters below the lead are still missing from enumeration. The investigation should stay attached to chain-member enumeration and to the exact generation in which it was obtained.
Build a useful diagnostic record
| Capture item | Why it matters |
|---|---|
| What to capture | expected and observed chain members, device instances, bus relations and PnP state |
| Current graph state | lead adapter, chain members and their PnP/power transitions |
| Supporting trace | device-instance IDs, lead/chain role, PnP problem codes, Dx states and start/power IRP ordering |
| Object identity | chain-member enumeration |
| Rejected condition | one or more linked adapters below the lead are still missing from enumeration |
Separate state from capability
- Enumerate all members before issuing the linked operation.
The comparison with ERROR_GRAPHICS_LEADLINK_NOT_ENUMERATED is especially useful: ERROR_GRAPHICS_LEADLINK_NOT_ENUMERATED is specific to the lead adapter.
Verify the repaired path
Fix missing device relations or driver installation and retry after complete enumeration.
- debug-layer, ETW or driver diagnostics no longer report the rejected chain-member enumeration contract during the same scenario.
