It means that the DNS Query (in your case in frame 193) has no corresponding response received by that host, so it sends the Query again. It happens when the DNS server doesn't response (in time) to the Query. Although not usual, it is not unheard of, e.g., when the DNS server is busy, or when it has to wait for upstream responses.
