Microsoft Content Linking Component
Microsoft Browser Capability
Microsoft Content Rotator
Microsoft Ad Rotator
Microsoft Logging Utility Component
Microsoft XMLDOM Component
Most of those come already installed with Windows 2000. Windows 2003 does not include:
CDONTS or the Microsoft components listed except xmlhttp.
To register them on a 2003 server place the .dlls somewhere on the server and go to that path in command line.
Then type "regsvr32 dllname.dll"
(replacing dllname.dll with the .dll file name)
That will register the components for use on your server.
