NS_E_NAMESPACE_NODE_CONFLICT

Where the condition occurs

This result (0xC00D138C) marks the operation targets the protected root node or another structurally non-removable node. The code identifies a narrow server contract, so diagnosis should preserve the object instance and the first native return.

Code-specific failure anatomy

A representative occurrence is when the operation targets the protected root node or another structurally non-removable node. Capture requested node path, operation verb, parent path and whether the target is the namespace root together with the object instance and the exact administrative or protocol request.

For a useful negative control, remove or update the intended child node instead of applying the destructive operation to the root.

The tempting but misleading response is stopping clients or clearing media caches; the conflict is in configuration-tree structure. That action does not test the distinction that matters here: node not found means the target is absent, while node conflict means the target exists but cannot accept the requested structural change.

Evidence that separates this code

Controlled comparisonUse a known-good object of the same type and vary only the precondition described as “the operation targets the protected root node or another structurally non-removable node”.

Smallest useful experiment

  1. Capture 0xC00D138C, the symbolic name, the exact API/administrative action and the first failure timestamp.
  2. Preserve requested node path, operation verb, parent path and whether the target is the namespace root.
  3. Perform one isolated experiment: remove or update the intended child node instead of applying the destructive operation to the root.

Related codes are different

Primary distinction: node not found means the target is absent, while node conflict means the target exists but cannot accept the requested structural change.

Changes that do not establish the cause

  • stopping clients or clearing media caches; the conflict is in configuration-tree structure.
