The checks for conficker and ms08_067 check for a specific status code
of 0x00000057, but do so by the name mapping to this value rather than
by value.
The name of this value was change from NT_STATUS_WERR_UNKNOWN_57 to
NT_STATUS_WERR_INVALID_PARAMETER in r24847, breaking these tests because
they were still searching for the "UNKNOWN_57" string.
This error was reported by Kit Peters.
