best: look at all the router, switch and server configurations. 100%
accurate but also 100% manual labor
next best: enable snmp on all the routers, switches and servers. Use
a network discovery tool (standalone or part of a network management
systems have) I haven't looked at it in years, but at one time NetViz
& Visio claimed the ability to discover your network and then generate
a pretty network diagram for you.
note that I haven't mentioned wireshark. It's great at what it does,
but it doesn't do network discovery.
