If I send the way you suggested I will alert all users connected to this server.
But I can't do this - if I'd send a Message like "Building 12 is burning - leave it!" all gazers will come to see it. So I need to send it to the affected people only. What do you mean with "retrieving the connection information von key servers"? Do you mean to receive the hostname where users are logged in? I've access to a Database where the location of the Hosts are saved and I do the net send command with the hostname as username. Thank you for your help!
