Servers are usually implemented as REQUEST/RESPONSE, what you are talking about is the server initiating a request to a specific client.

For this you can do the following :
1) Setup the reverse process on the client and server where the server is the client and the client is the server.

2) Implement a polling mechanism where the clients send a request to the server and gets the messages for it (say every 5 sec).

Option 2 is better.
