I have used it on NT, 2000, and XP sucessfully. I uninstalled everything and re-installed LabVIEW. The server starts ok until you try to use it. I also try to read web pages with the datasocket read and I get nothing. Have you run it sucessfully on ME? I am mainly interested in reading web data from datascoket. I can do it other ways, of course. But I was just wandering if there is a flaw in ME that does not allow it. Thanks for your input.
