I have read in a number of books that it is advisable not to install networking when you first install the Windows NT/2000/XP operating system onto your networked computer. This is to give you the opportunity to get your system up and running successfully as a stand alone system before adding the complexity of networking. This should also make troubleshooting any problems that occur during the original installation much easier by allowing you to resolve the original setup and networking problems separately.
If you will be networking the computer straight away then you can proceed to install networking as soon as you are sure that your initial stand alone installation is working correctly. To start the networking install just right click on network neighborhood and select properties. If this icon doesn't appear on your desktop then go to the control panel (either from the settings option in the start menu or from the icon within my computer) and then go into networking. This will take you through the same networking setup as you would have gone through as part of the initial install ad you not selected to bypass it there.
The problem comes where you decide to install networking on your system at a later date rather than straight after the initial install. Chances are that you will have installed one or more service packs onto your system since the initial install was done. When you then install networking from your original media the parts of the operating system that are installed/upgraded by installing networking will not be consistent with the rest of the operating system. One possible result of this is that the server service installed as part of the networking service will refuse to start giving an error message instead (not enough server storage to start server service).
To fix this problem you need to reinstall the latest service pack onto your system so as to upgrade the networking components to the same version as the rest of your operating system.
