NS_E_DUPLICATE_NAME
Diagnosing NS_E_DUPLICATE_NAME
0xC00D0036 means an administrative operation attempted to create or rename a Windows Media Services object to a name already present in the owning collection.
Evidence to collect
- the exact requested name, including whitespace and normalization/case as supplied by the API;
- the object collection or namespace in which the name must be unique;
- the existing object's identifier, type and configuration generation;
- the create/rename call and the configuration source that supplied the conflicting name.
Focused test
Enumerate the owning collection through the same administrative object and look up the requested name. Decide whether the existing object should be reused, renamed or removed. Testing with an unrelated unique name can confirm the uniqueness check, but it does not identify which configuration produced the duplicate.
Verification
Repeat the original create or rename operation after resolving the name collision. Confirm that the intended object is created under the expected identity and that no stale administrative object recreates the old name.
