Failed to connect to server "%MACHINENAME%

Hi;

I have problem with opening report with crystal report 2013 EOM ,  i got this strange exception  I have google it and didnt find any helpful data

"Failed to connect to server "%MACHINENAME%".Error returned from Windows Sockets API getaddrinfo: 11001."

i am using this code

tempFilePath += "Evaluators Trend.rpt";

            ReportClientDocumentClass crystalReport = new ReportClientDocumentClass();

            object path = (object)tempFilePath;

            crystalReport.Open(ref path, 0);

can you please  advice how can i avoid this issue .
