NPower Seattle has a Network Documentation Template which is in Word. This is a great start for documenting your computer network. The file is called SBS2003template.doc which suggests it might have been modified by one supplied by Microsoft, and it includes inserted Visio files to show the networking diagrams. If you are a MS shop this will work out of the box. If not, you can easily modify it in OpenOffice, or Pages, or whatever. The object of documenting your network is not necessarily perfection…but to have something to give you a clue when things start going haywire.
