The default, as you know, is C:\Program Files, For XP, which I'm using (so Win 2000 should be the same) you can change this by going to Start > Run, type in "regedit" (without the quotes) and navigating to
Click on the Current Version folder in the left-hand pane and the contents open in the right-hand pane. Double click on "ProgramFilesDir" in the right-hand pane and change C:\Program Files to your desired destination. Then exit the registry. I'm assuming you will take the necessary precaution of backing up the registry before you make any changes, BA.
