What do I enter in the System Field in Crystal Reports in order to save a report to Crystal Server?

I installed Crystal Reports 2013 on my computer.  I installed Crystal Server 2013 on my server.  I want to save reports to Crystal Server.  I did a “Save As” and selected “Enterprise” from Crystal Reports.  I got the Log On to BusinessObject Enterprise box.  The System field defaulted to my computer name.  I assume I need to enter the server IP address or other server information in the System field, but I am not sure exactly what this looks like.  I have tried several things, but nothing works.  The error message I get is “Transport error: Communication failure. (FWM00001)”.  I am signing on with the Administrator sign-on and password which I know works as I have used it to log into the CMC when remoted into the server.  What do I enter into the System field?  What is the format?  Or should the server information be enter elsewhere in Crystal Reports?
