MF_E_GRL_EXTENSIBLE_ENTRY_NOT_FOUND

MF_E_GRL_EXTENSIBLE_ENTRY_NOT_FOUND is a lookup failure inside Global Revocation List processing. The requested item is identified by an extension GUID, so the useful diagnostic data is the GUID and the GRL version, not the media subtype or decoder CLSID.

Log the exact extension request

  • Record the extension GUID passed into the GRL-related operation and the component or protection system that requested it.
  • Record the installed GRL version and any preceding minimum-version policy result.
  • Check whether the caller expects data introduced by a newer revocation-list format or servicing level.

This differs from MF_E_GRL_UNRECOGNIZED_FORMAT: the current reader has parsed the GRL far enough to perform a GUID-based lookup, but the requested extensible entry is not present. It also differs from a component revocation result, which identifies a rejected component. Do not substitute a different media type or topology node; investigate the trust-data version and the specific extension request.
