Hi Benjamin.

I did something similar to this in Visual Basic using windows functions (DLL) in those days. I called it broadcast.

However, your issue is not very difficult because those clients that are online receive your message, but anyone just connecting will not receive it after the broadcast.

What you have to do is to store and forward your messages for the clients that are offline. You can achieve this by storing your message and client ID on a database or a file for the clients that are online at the time of sending message out, then you will have a sort of service program that will forward the message later for new clients just connecting to the network.
Remember every system has a unique computer name (ID) on windows network.
When you send the message out, you keep the IDs of those online and the service program will later forward to new online clients and store their IDs too.
Note that you may also have to generate unique message ID also to filter.
