I was in a computer lab during class and one of hte students made a windows message pop up on everyone's screen. It said:

Windows Message
From TC00123 to WORKGROUP (or something like this)
then a brief message regarding class
at the bottom of the small window was a OK button

I won't to know how he did this so I can mess with my family on my network at home???

For the class, you can stop it if you want by disabling the Messenger service.

Ok thanks, sramesh2k you answered correctly and will get the points.  I just have one more quick question.  Is there anyway I can specify the place the message came from.  Instead of it saying my computer name is there any way a can specify a name that the message is from.
