UDP wont read

[altenbach]

Well, it was just a wild guess, since multicast != broadcast and I did not know your OS.

Probably something else is wrong. It is dificult to understand how UDP read can complain about an invalid input in this scenario.

• Have you played with other options, e.g. change the "UDP multicast open" to read/write.
• Does it work if you temporarily disable the "other" network card in the OS?
• Have you disabled all firewalls?
• Do you get the error immediately when running the VI or only after a packet arrives?
• Are both computers on the same subnet?
• Can you show the output of "ipconfig /all"?

I have already tried the methods you have mentioned before posting my question in here. It does not work. I get the same error. The error is almost immediate at the UDP read stage. I will post ipconfig log soon.
