I develop intranet application using ASP.Net 2.0 with VB language.
I have some modules that necesarry send messages to users.
Currently, my Bulletin Board shows pop up windows if there are messages to users.
It reads SQL Server table every 5 minutes using Web Service.

For others modules (GA-Payment, User ID Maintain),
I have planned to use Net Send function that provides by SQL Server with activating Job Schedule.
But i hesitant, if it could decrase my SQL Server or my Server performance.

So, do you have experiences how to send message to users with ASP.Net ?

Thanks and Regards,
