Hi Barry,
What do you mean "it doesn't work"? What kind of errors are you seeing? Also, you only specified the file name (data.vi) when opening a VI reference. Try specifying the whole path to the VI. Also, you might want to make sure you are able to ping your other computer from the start (to see if this is a LabVIEW issue or a network issue).
Hope this helps,
