Best anonymous scan utility to determine network device/OS type

Unanswered Question

The problem is to scan a network Ip range from an anonymous host and determine what type of devices residing on that network. Here are some device criteria:

1) May be Cisco, 3com, HP, etc. Device manufacturer is unknown

2) Device might be firewall, switch, hub, router, etc.

3) Device may be managed to a limited extent. In other words, most management protocol may be shutdown.

4) Do not have logins, password or SNMP RO/RW string for these devices.

What is the best app that can run from windows or Linux that could determine with the greatest degree of success, what types of devices these are?

Some general ideas: OIDView, Nessus, NMAP, SW toolset?

thx in advance,
