Winsock question

[tedsmith]

The proposed setup is ONE "master" computer sending the same info one way out to 500 "slave" computers. This is over a WAN with lots of routers and firewalls enabled only to the IPaddresses and port ranges used.
No return message is necessary.

Question Is it possible to have ONE Winsock in the master computer connected and sending to ONE Winsock in each slave in one operation?

This would be so the master can dump info one way to all the 500 slave computers in one operation. If so how would you arrange the connection and sending process?

I know I could use multiple Winsocks in the master or send them one after the other but was hoping to do it all in one go to do it faster.
I have read there is a limit to the Winsocks per computer that you can have open at one time so some would have to be reused, opened and closed in turn so the operation could occur multiple times in sequence with that option.

Well, you could consider multicasting. It isn't something I've tried in VB, and I suspect it is far from trivial (I also suspect it would involve some substantial rewriting of your existing code). Here's a starter page for your bedtime reading:
