A number of problems, particularly with your internal network, will go away. However, do not install RC2 as an upgrade to Beta 3.
Installation is astonishingly easy.
As soon as Windows 2000 Professional comes up, it asks for networking information including the domain name. A few seconds later you are on your internal network, and in our case, since the Rebel NetWinder is constantly on line to the Internet, the new Windows 2000 Professional workstation is on the Internet. Within a minute after installation was finished I was using Internet Explorer to browse the Internet. This is really fast installation. Of course that's only if you are using reasonably standard hardware.
