Question : WIndows 2000 different versions?

This question in relation to my past question here:

http://www.experts-exchange.com/Operating_Systems/Win2000/Q_20188170.html


*****

What is the difference between these versions of windows:
Windows 2000 Advanced Server (25 clients)
Windows 2000 Server (10 clients)
Windows 2000 Server (5 clients)
Windows 2000 Server Internet Connector (unlimited clients)

I went to Microsoft's site and the information is not very clear.  I need to set up a way where I can host my own web sites at home based on my CABLE connection.  I only have Windows 2000 Pro and wanted to find out what really is the best choice for such an applicaiton?

Thanks
