network topology in LMS only display devices with cdp client.
if you want to monitor your windows server using the same map, you can:
-download one cdp client (http://www.tallsoft.com/cdpclient_setup.zip)
- install the client on the windows machine (i hope cdp client has no trojan!!!)
-on the server, edit SNMP service and in the security tab, add LMS IP address
-in LMS add the windows machine with adequate SNMP community
give it some time, then you will have your server displayed in network topology !!!!
