The 10060 socket connection error code indicates that the socket connect request timed out. This error can occur for a variety of reasons. This basically means that no response (either positive or negative) was received from the remote host when the TCP connection attempt took place. One reason this may happen is because a firewall is blocking the response from the server.
135 = the port
To verify the ability to connect, remote into the robot hosting the rsp probe and use telnet to verify.
telnet 184.108.40.206 135
This also assumes that the WMI service is running on the remote Windows system and is using the standard WMI port (135). If the WMI service on the remote system is not using port 135, the device cannot be monitored with the rsp probe since the probe hard-codes port 135 for WMI as documented in KB126217 : Is rsp probe able to monitor servers where WMI/ssh uses non default ports
