NS_E_DUPLICATE_ADDRESS
Diagnosing NS_E_DUPLICATE_ADDRESS
0xC00D0037 means the requested Windows Media Services network address/binding conflicts with one already assigned. This is an address-allocation problem, not an object-name collision.
Evidence to collect
- the exact IP/interface/address value, port and protocol or server object that requested it;
- existing listeners, publishing points or plug-in bindings using the same address;
- whether a wildcard binding overlaps the requested specific address, or vice versa;
- the service/configuration generation in which both bindings were present.
Focused test
Enumerate the active server bindings and identify the owner of the conflicting address before changing it. If appropriate, stop or reconfigure only that owner and retry the original binding. A different free address is useful as a control but does not prove the intended address is available.
Verification
Recreate the requested binding and confirm that the same address, port and protocol are owned by the intended server object without displacing another required listener.
