    This could have been fixed but I'm pretty sure I recall this sometime ago as
    an unresolved bug. Can you get this to work from a standard console app?

    Yes this will run as a console app. Also as said simply changing the socket
    type to TCP will also work. You state this could have been fixed... Can
    you point me anywhere where that shows how to make this function. I posted
    the same question a few months back and received no response.

    Hi Bryan,

    I recall a conversation about it but have no information if it has actually
    been fixed - or if indeed this is actually a problem.

    Its a bit strange that UDP works from console but not from asp.net - kinda
    suggests its a permissions problem or it has been designed that way - you
    probably know more about UDP than I do.

    You might need to rethink how you could architect your solution a little
    differently in light of this. Sorry I cant be any more help.....I'm kinda
    guessing here as the conversation was quite some time ago.

    Well, this stopped with SP4. Prior to that everything worked to my
    knowledge. I think its really cheesy that M$ cant chime in here cause I
    know there cruising the groups.

    I am 100% sure it is a permission problem. I don't think it is by design
    because why would they give me access to TCP but not UDP. Also no matter
    how you try security it still yeilds the same results. I fully understand
    that UDP is a send and forget but its kinda lame if it turns out to be by
    design that M$ doesn't think anymore of its developers than to completely
    block access.

    Guess I should look at porting it over to J2EE. Probably easier anyway.
