I love Windows Server 2003. It helps that I worked on both it and 2003 sp1. It is a very stable, mature, reliable operating system. It also makes a great workstation. I find it surprising that hardly anyone has sounded the horns over 2003 sp2. But it is out there. and it rocks. oh how it rocks.
Get it here
Later on I will show you how to turn Server 2003 into a workstation. It isn't as weird as it sounds.
