RPC_S_INVALID_VERS_OPTION
Version matching controls which interface registrations qualify
RPC_S_INVALID_VERS_OPTION means the caller supplied a version-selection option that the RPC endpoint-map or namespace lookup API does not accept. DCE/RPC lookups can compare interface UUIDs and versions using defined policies such as all versions, compatible versions, exact versions, or major-version matching, depending on the API.
The option is not the interface version itself. Passing a major or minor version number in the version-option field is a common wrapper or serialization mistake.
What to check
- Log the interface UUID, major/minor version, and version-option value as separate fields.
- Use the documented
RPC_C_VERS_*constants accepted by the specific inquiry function. - Do not assume every RPC API supports every version-matching mode defined elsewhere in DCE RPC.
- When compatibility is intended, verify the server major version and minor-version rule rather than broadening the lookup blindly.
Endpoint mapper matching is precise: Microsoft documents exact interface UUID and major-version matching, with compatible minor-version rules for endpoint resolution. Correct the selection option before diagnosing missing registrations.
