Using the smbclient

Hi,
I am trying to use smbclient to send message to a windows machine.It is showing "connection failed message" . After googled I came to know about "smbfind" which will give me the nodes in my network. In that list the machine name was not present where I was trying to send the message.
Now I would like to know how can I check in windows machine whether it can receive a popup messages or not . Also what shall I do to make that windows system able to receive popups.

Thanks

Not clear if you are looking for.

Windows Service name: Messenger
