There are several things that could be causing it.

1. You may have to use the agSwapBytes funtion in the Windows API.
    You would use this API on the message you are going to send.
    Your news sever could be using a motorola processor and your PC is
     more than likely an Intel processor.  They somtimes have the bytes in
certian types
     of data in reverse order of each other. (hope that makes sense.)
     I have had this error my self and this was one solution.

2. Make sure your winsock control isn't in "listen" mode.  Check the
"state" property of the winsock control.
    If some how you are in "listen" mode you can't send messages.

I mess with winsock controls connecting to UNIX serves all the time...these
are just some of the problems I have encounterd.
