Does anyone know of a peice of software (preferably free) in which it allows you to monitor the computers on your network, and check updates, and see what patches they do or not have, and also see other information about the computers on your lan?

Is there any such software that is free?

I did find a program called 'LANguard NSS' which does exactly what I want. except I have no clue how to use it. I mean I can scan my local computer, but when I go to scan my IP Range of my computers, it does not work. And I dont know how to configure it with my Personal Firewalls on each workstation....any one have a clue?
