I am a newbie to Linux and Samba

I am setting up a samba server ( Fedora core 1)to replace the obsolete Novell 4 in my office. The file sharing under user level security work perfectly and the printing using CUPS is fast and efficient.

However, users complainted that they did not receive a popup messages (windows 200/XP) after the printer has finised printing as they did using Netware 4.

Is there a utiility that can send a popup messages to windows client after the print job is completed?? or is there something I have misconfigured so that samba print notification is not able to send to the windows client?

Messenger services in Windows clients are all enabled and running

Thanks
