You would not see retransmission or resets when using UDP as a transport protocol. However, UDP makes use of ICMP as a error reporting protocol.

During the course of troubleshooting connectivity issue, you might also see in the network trace that a machine receives packets but does not respond to. In such cases, there could be a drop at the server level. You should enable firewall auditing on the machine to understand if the local firewall is dropping the packet.
