I am a Microsoft MSDN and have an Action Pack version of Small Business Server 2003. It came with 5 CAL's and I want to add more CAL's. I called Microsoft and their answer was, sure you can buy a 5 user retail CAL... and it might work, go for it. I don't want to drop $350 for nothing. Does anyone have any experience with this?
