I have a startup script that runs on machines (not a login script, but a startup script). It occurs as the machine starts up. I was wondering if there was a way I could display a message in the startup box?

This is the area that displays "Preparing Network Connections...", "Applying Group Policy", "Installing Managed Software: Microsoft Office", or "Running Startup Scripts".

Obviously there is a hook somewhere to stick a message in there. Anybody know what this is?
