MF_E_NET_UNSUPPORTED_CONFIGURATION

MF_E_NET_UNSUPPORTED_CONFIGURATION means the selected network-source configuration is not supported by the source, protocol, or platform.

What to check for MF_E_NET_UNSUPPORTED_CONFIGURATION

Compare application-set network properties with the protocol capabilities of the selected source.
Disable unsupported optional controls rather than changing unrelated transport settings.
Use logging to confirm which protocol and transport were actually selected.

Diagnostic interpretation of MF_E_NET_UNSUPPORTED_CONFIGURATION

MF_E_NET_UNSUPPORTED_CONFIGURATION has the HRESULT value 0xC00D4293. AllStat records the condition as “The specified configuration value is not supported.%0”. For MF_E_NET_UNSUPPORTED_CONFIGURATION, in practice, interpret that wording at the boundary owned by Media Foundation or Windows media pipeline state, rather than treating the value as a generic Windows message.

Evidence to capture for MF_E_NET_UNSUPPORTED_CONFIGURATION

Record the exact COM method or Windows API, its input object, the calling thread, and the full 0xC00D4293 value before a wrapper converts it to an exception or Boolean result.
Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions MF_E_NET_UNSUPPORTED_CONFIGURATION or the mf / net / configuration operation.
Reproduce MF_E_NET_UNSUPPORTED_CONFIGURATION with the smallest valid input and note whether the result changes with identity, architecture, service state, or target object.

Retry and recovery for MF_E_NET_UNSUPPORTED_CONFIGURATION

Retry MF_E_NET_UNSUPPORTED_CONFIGURATION only when the owning API documents a transient state or after the condition described as “The specified configuration value is not supported.%0” has changed. For MF_E_NET_UNSUPPORTED_CONFIGURATION, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
