Error = 66 is LabVIEW: The network connection was closed by the peer.
This indicates the peer (i.e. the other node) closed the conncetion. This leads me to believe the the "issue" is not on your XP machine, but the other node. I have seen this error when doing TCP/IP based interactions with a LV-RT system. In my case there was an issue with memory resources. In that case that was the last message I recieved before the RT app crashed. That being said I will try to address your Q's. HOw can I avoid that error 66? This can not be answered without knowing more about "the other node. What am I doing wrong? Turn your attention to the "other machine". How can I get rid of error 66? Please provide more detail about what is going on with the other machine. Posting code usually helps us help you. Trying to help, Ben
