I am testing out a LabVIEW app which has a TCPIP interface. To test it I am attempting to send commands via the TCP from a test VI resident on the same machine. When running on my desk PC it works fine. However, on the test rig PC it refuses a connection and comes back with error 63 or sometimes 66, basically connection refused. I am connecting using the loopback IP 'localhost', although I have tried 127.0.0.1 and the PC's own address.
Regarding VI server connections, I have checked that the settings are the same on both machines. I tried adding '*' to the machine access section to allow access from any PC, but no joy.
Thanks in advance,
Ian
