Hi,

I have installed Reflection for desktop evaluation and when I am trying to connect IBM 3270 terminal, I am getting error: Host refused to connect.

what should I fill in Host name?

Check with the Systems Programming staff (the administrators) for the mainframe system you wish to connect a session on. They will have all the information you need to connect with their mainframe.
