It is inferred from code inspection that the test failure is due to `FindFirstFileW` failing with `ERROR_NETNAME_DELETED`. This does not appear to be an error more serious than `ERROR_NETWORK_UNREACHABLE` or `ERROR_NETWORK_ACCESS_DENIED`, hence ignoring it as well is unlikely to cause problems.

As the failure looks to occur only for list item 7 initialized by the `MethodSource` method `pathProviderWindows` in the `GetCanonicalPath` test, namely `\\\\server\\share\\foo\\bar\\gus`, an alternative would be to remove this path from the test and not make any implementation changes.
