What the server is validating

This result (0xC00D1395) marks child enumeration requested an ordinal outside the current child collection. The most useful interpretation starts with the Windows Media Services object that returned the HRESULT.

Verification outcomes

Controlled comparison

Use a known-good object of the same type and vary only the precondition described as “child enumeration requested an ordinal outside the current child collection”.

Test the owning precondition

Capture 0xC00D1395, the symbolic name, the exact API/administrative action and the first failure timestamp.
Preserve requested index, current child count, namespace generation and whether callbacks modified the collection during iteration.
Perform one isolated experiment: snapshot or re-read the count and enumerate within that same generation.

Do not merge nearby HRESULT values

Primary distinction: node not found is a named lookup; index too large is an ordinal/count contract.

Nearby result	Different condition
`NS_E_NAMESPACE_BAD_NAME`	a nonempty namespace node name violates the server naming grammar.
`NS_E_NAMESPACE_EMPTY_NAME`	a create or lookup operation supplied an empty node-name component.
`NS_E_NAMESPACE_WRONG_SECURITY`	an existing node is being written with a different security classification.

Changes that do not establish the cause

subtracting one repeatedly without checking collection changes.
