Forms in Windows Taskbar

I am a newbie to .NET development...

I want to implement something very similar to MSN Messenger Alerts, My application is a client application, sits in windows Taskbar and when there is a alert, it pops-up a window displaying the alert. I dont want user to resize or move the alert window....

Any ideas how can I do that?

Thnx in advance
