I am building a replacement for WinPopup and I would like to be able to send messages to people using their username and their computer name. I also need this for backward compatibility with the original Microsoft edition of WinPopup.
When a user sends a message for the original WinPopup it is sent from the "Username" of that person so my program cannot determine the computer that sent the message. My program must send the message to the computer name and not the username.

I am using a combination of windows 98 and 95 so the Windows NT way of doing this is no good. If someone has a way of working this out could they please reply urgently.

Thanks
