I recently started working as the network admin for a smallish research business with around 100-150 employees and about that many computers.
There is currently very little (no) documentation about the network and I have been asked to write up some "official" document, i.e. what machines do what, where they are, what ethernet ports are actually active etc.
The network is a workgroup setup and I don't have passwords to any of the employees machines. I do have admin privileges on the DHCP, DNS and nortain Antivirus server.
Can anyone give me advice on how they would go about mapping the network. What info I should gather how I shoud store it etc. Also as part of this I would like to set up some type of monitoring system that would alert me if a server goes do or if a client starts sending doggy traffic etc.
I have a floor plan for the complex and was think of adding the information about our network on top of that.
Any bright ideas.
