ERROR_VID_INVALID_OBJECT_NAME
ERROR_VID_INVALID_OBJECT_NAME is HRESULT 0xC0370005 in the VID object naming area of the Windows virtualization stack. The built-in message names the immediate result; the useful custom context is the exact boundary: syntax or semantics of a partition or message-queue name passed to VID. Record the first returning operation and host-side event before a management layer retries or translates it.
Locate the failing boundary
The name fails the internal object-naming contract before normal lookup or creation. Preserve exact characters, length, encoding, terminator handling, and whether the value was generated from an external VM name.
Hyper-V architecture documentation identifies VID as the component that provides partition, virtual-processor, and memory-management services., many ERROR_VID_* values describe internal host objects rather than a public API that administrators should call directly. Accordingly, diagnose this result through the named object/state, the VMMS or Worker event chain, and the operation that produced it; do not invent a user-mode VID call from the constant name.
Neighboring result: NAME_TOO_LONG identifies length specifically; NAME_NOT_FOUND concerns lookup of a syntactically valid name. INVALID_OBJECT_NAME is the broader validation failure.
Build an incident record
| Evidence | Why it changes the diagnosis |
|---|---|
| Raw name | Record escaped UTF-16 code units, length excluding and including terminator, and source field. |
| Object type | Identify partition versus message queue and the operation using the name. |
| Normalization path | Keep trimming, case conversion, GUID formatting, and prefix construction steps. |
| Control name | Use a minimal known-good generated name through the same wrapper. |
Preserve identifiers and counts without dumping guest secrets or unrelated memory. Useful this result timestamps include the last successful operation, first failure, any automatic retry, and the object-generation change that followed.
Run narrow checks
- Reject embedded NULs and invalid serialization before the VID call.
- Keep display names separate from internal stable identifiers.
- Test boundary lengths and non-ASCII input without lossy conversion.
- Do not sanitize by silently changing identity; log the mapping explicitly.
Test the smallest supported create, lookup, initialize, or resource request that preserves the named condition. In the result reproduction, change one count, identity, or lifecycle step at a time and capture the first host event before retry.
Interpret three controls
Across these controls for it, preserve syntax or semantics of a partition or message-queue name passed to VID as the boundary under test.
| Control | Interpretation | Hold constant |
|---|---|---|
| Fresh owned object — this result | A clean lifecycle changing this result implicates duplicate initialization, leaked ownership, stale lookup, or incomplete rollback. | Preserve request flags and topology while changing only object generation. |
| Same request on a compatible host — it | If it follows one host, compare resource limits, topology, build, and inventory before altering VM data. | Use the same request and leave virtual disks unchanged in the result comparison. |
| One operation parameter — it | Change one count, name, identity, or state transition. If it moves, the selected boundary is causal rather than the VM as a whole. | Keep host build, VM ID, and returning operation fixed for it. |
Keep neighboring states separate
A restart may release internal objects and make it disappear while erasing registration, ownership, resource-count, or teardown evidence. Capture the first result event chain before recovery.
Prove the correction
A valid fix accepts documented names, rejects malformed input deterministically, and preserves stable object identity across restart. Repeat the original operation under the original supported conditions and retain one deliberate negative control. A management command succeeding on a different object is not sufficient to close this incident.
