FWP_E_INVALID_RANGE
FWP_E_INVALID_RANGE means an FWP_RANGE condition is malformed. Its endpoints must be comparable values of the expected type and must describe a valid lower-to-upper interval.
What to verify for FWP_E_INVALID_RANGE
- Confirm the lower and upper values use the same WFP data type.
- Check that the lower bound does not exceed the upper bound.
- Use a range only on a condition field and filtering layer that accept range matching.
Diagnostic discriminator: Inspect both endpoints and their WFP data types. A lower bound above the upper bound, mismatched types, or a layer that does not support range matching distinguishes this from ordinary filter mismatch.
