A great tool allowing you to easily document your network and what is installed on it is LANsurveyor.  It will create a network diagram in Visio format in just a matter of minutes, after going out and scanning the network for connected items (PC’s, Laptops, Routers, Printer, etc).  For a limited time, solarwinds is offering this add-on free (a $499 value as they claim), by just filling out their registration form.   *NOTE: As they themselves claim – Visio 2007 is required*
