From what I see, that message is (possibly) generated when:
a. User is trying to connect with a system which doesn't want such or is not on the same wavelength.
b. A firewall is blocking the connection attempt.
c. Invalid IP address or other nonrecognition of computer
trying to make connection.
So, my question is...what is it that you are trying to do when you get these messages?
