What does HRESULT 0xC1250100 (WDSCP_E_INVALID_CONFIGURATION) mean?

WDSCP_E_INVALID_CONFIGURATION

WDSCP_E_INVALID_CONFIGURATION belongs to the WDS Content Provider layer. A WDS transport namespace carries provider configuration through its Configuration property, and the provider initialization path consumes server-supplied initialization settings before content is opened or read.

Validate the provider configuration at the namespace boundary

• Read back IWdsTransportNamespace::Configuration for the failing namespace and log the exact value supplied to the provider.
• Confirm that the namespace references the intended content provider; configuration syntax is provider-specific and should not be normalized by generic transport code.
• Reject empty/invalid configuration before starting active transmissions so the failure is associated with namespace registration rather than a later read.

The WDS management API intentionally treats content provider selection and provider configuration as separate namespace properties. That means a registered DLL can be correct while one namespace still carries an invalid configuration string. Compare the failing namespace with a known-good namespace using the same provider. The content provider error should be fixed in configuration, not by changing multicast client callbacks or slow-client policy.
