Re: [nv-l] MLM on Windows

[Jane Curry <jane.curry@skills-1st.co.uk>]

My suggestion about netmon.seed was to ensure that, IF NetView polled 
these nodes behind the firewall, then he would poll using SNMP rather 
than ping (in case your MLM goes down, say).  I assume you have netmon 
configured to use MLM for status polling so your MLM should have been 
given control for them and, as you say, everything goes green.
You probably need to educate your users NOT to select any of these nodes 
and do Test -> Ping or they will probably turn red until the next MLM 
status poll.
Cheers,
Jane
