This method of developing an intranet has only been tested in a lab on computers not connected to the Internet. You will need to make changes to these instructions if your lab or building is already connected to the Internet. Very likely you will need to make changes to the IP address settings to coincide with the ones already in use. If you do not, conflicts will arise causing your intranet not to work. You may also need to change the way in which the IP addresses are assigned to your computers.
Some systems automatically assign IP addresses on an as needed basis.
If your computer lab or network is already connected to the Internet, it may be a good idea to setup the intranet servers on a machine other than your file server. This will prevent loading down of the server that is running the lab. The first thing you will need to do is to assemble the necessary software for both the server and client computers. One piece of the software you may already have. This control panel needs to be in the control panels folder of the System Folder for the intranet to work.
